__________________________________________________________________________
These pools prediction programs have been updated for use with the
expanded CEEFAX league table data for the 1988/9 season.
Some makes of adaptor cannot implement multiple page grabbers, necessary
to give a reasonable data access time, due to their design. This cannot be
overcome by software, and is a direct result of the type of teletext
reception chip used in their design. Such adaptors will not be able to use
these routines.
The routines have been adjusted since their last broadcast to cater for
the various page layouts and quantity of sub-pages occasionally
implemented by the CEEFAX editors. Other adjustments may be necessary in
the future!
__________________________________________________________________________
OCT/DEC 1988: The programs have been modified to cope with the various
different pages on which the results and/or fixtures lists can be found.
Initially, CEEFAX used page 332 for the fixtures, and 331 for the results.
However, this protocol is frequently not adhered to. The data for either
routine must now be sought from either page, with the added complication
of either page not being transmitted at all on occasions.
To cope with this, the routines MATCH and RESULTS now scan the most
obvious page first. If the appropriate data is not found there, the other
page is searched. If the relevant page is not found within a certain time,
it is assumed it is not being broadcast. Because of this, it is not
possible to estimate how long on any particular day the routines will take
to find the appropriate data. It may find it within a few seconds, or it
may take several minutes, depending upon the level of searching that has
to be done to find the pages! Please be patient.
_________________________________________________________________________
** Please note **
Despite the footnote to this text, many people have tried, and failed, to
run the RESULTS and MATCH programs on Morley or Solidisk adaptors. These
units cannot implement the advanced features incorporated into these
programs. This is a hardware constraint, caused by the type of teletext
chip used in their design. Even the ATS ROM cannot add these features as
the adaptor hardware itself will not allow it.

Pools Prediction Programs:
==========================
This suite of programs uses CEEFAX data to predict the football results
for the current week. There are three different programs:
1. Match
2. Foot
3. Results
1. Match:
=========
From about Tuesday onwards, BBC2 CEEFAX transmit the following Saturday's
fixture list. The program "Match" will analyse these transmissions and
create a data file of match data on disc. This file can then be used by
FOOT as match data, to avoid having to type in by hand the teams playing
in each match.
The program will check to see if the fixtures list is actually being
transmitted. If it finds it, the CEEFAX pages required are listed on
screen, with each found page being reported.
The data file is created automatically as each page is found. Several of
the system's page grabbers are used, which gives a considerable time
saving over previous versions of this program. As processing is carried
out, the match number (directly relating to the pools coupon number) of
each match found is briefly displayed on screen.
The program will inform you if the fixtures list is not yet available from
CEEFAX. If this is so, the program should be run again later in the week.
2. Foot:
========
This is the main prediction program. Before using this, however, some
things must be noted. The program uses CEEFAX data to compile information
from the league tables about each team playing in the league. This
information is then used to predict the outcome of the match. It is
important to understand how this process works, as the user must provide
his own algorithm using this data! The information is kept in the
following arrays:
ITEM HOMETEAM AWAYTEAM
==== ========= =========
League points gained: PT(m) PT(n)
Total matches played: P(m) P(n)
Goals scored for team: F(m) F(n)
Goals scored against team: A(m) A(n)
Games lost: L(m) L(n)
Games won: W(m) W(n)
Games drawn: D(m) D(n)
A formula must be devised to use as much of this information as is
necessary to produce a winning solution. The formula must be of the form:
= (Strength of away team) - (strength of home team)
i.e. it must calculate a value for the home team, then a value for the
away team, then subtract one result from the other. Calculations that
produce results closest to zero are considered more likely to be drawn
games than those producing high values. So two teams producing a similar
number will be more likely to result in a draw than two teams producing
very different values. The formula included in the program is very simple,
and only compares the two teams league positions. To give some idea of how
to enter a suitable formula, some examples of calculating team strength
follow:
=(PT(m)+(D(m)*3)-W(m))-(PT(n)+(D(n)*3)-W(n))
This uses points gained, drawn games and games won for each team
=(P(m)/D(m))-(P(n)/D(n))
calculates the number of matches played, divided by the number of matches
drawn for each team
=PT(m)-PT(n)
calculates the number of points gained for each team
=(P(m)/L(m))-(P(n)/W(n))
studies the number of games lost by the home team, and the number of games
won by away team (a perfectly "legal" if not very logical formula!)
These formulae can be very simple such as:
=D(m)-D(n)
which compares the number of drawn matches of each team, or more complex,
such as:
=((L(m)+(P(m)*20))*D(m))-((W(n)+(P(n)*20))*D(n))
which considers matches drawn, lost, won, etc. A winning solution is
likely to be even more involved! It should be remembered that,
particularly early in the season, several of these values will be equal to
zero, and an error will result if your formula includes a 'division
by zero'!
Your desired formula should replace the one given in line 5000 of the
program "Foot", then the new version saved to disc before use.
When the program is run, you are asked if the match data is to be read
from disc. This is only possible if it has previously been saved to disc
using the program "Match" (see above), but will save a lot of time if it
can be read from a disc file.
You are then asked if the league details are to be read from disc. Again,
this may only be done if this data has already been saved to disc from a
previous run of the "Foot" program. (The data is automatically saved to
disc each time "Foot" is run.)
If the league data has been taken from CEEFAX, you will then be offered a
chance to see (or print out) a list of the team names and their
corresponding numbers. This option is not available if the data is read
from disc, as the program then relies on a compressed version of the team
names which may not be very much help to you! The team names and numbers
will be needed later if you have opted to manually enter the fixtures
list. If a printout of this list is required, simply set your printer "on
line" before selecting this option.
The program proceeds to request the match data in numeric form. If the
data is read from disc, the fixtures list will be read in, stopping at the
bottom of each screen to allow you to look for any necessary corrections.
Press SHIFT to scroll the screen. If this data needs to be entered
manually, type in the appropriate team number at the prompt, as taken from
the team list offered earlier. Any corrections can be made after all the
match data has been entered.
The program will then calculate the most likely 18 matches to result in a
draw. If you want this selection sent to your printer, ensure that your
printer is "on line". Otherwise it will be sent to the screen only.
3. Results:
===========
During the execution of "Foot", a data file is created on disc of the
matches predicted. "Results" will analyse the actual results as
transmitted by CEEFAX, and calculate the maximum pools points that have
gained using the given forecast.
If you use a pools entry with more (or less) than ten selections, the
appropriate line at the beginning of the program must be altered. The
program calculates the maximum points possible using a Full Perm plan,
but also presents the results in pools points format for normal checking
of a coupon.
The results are broadcast on BBC1 on a Saturday afternoon/evening, and
then are transferred to BBC2 for the early part of the following week.
The program detects the day on which it is run, and will select the
correct channel and page numbers automatically. (i.e. if run on Saturday,
it will select BBC1, pages 331 onwards, but if run on, say, Monday, it
will select BBC2, page 341.) A check is carried out to ensure the actual
results are obtained, and not the half-time results or other data. A
report will be given, and the program terminated if the results are not
found.
If a match is declared void, or a result decided by the Pools panel, the
correct pools points will be found. Such situations will be reported when
the results are listed by the program.
This program uses several of the system's page grabbers, resulting in a
much faster execution time than from previous versions. Whilst each page
from CEEFAX is being processed, the screen will indicate briefly which
particular pools coupon match number is being studied at the time.

Note: The programs have been written to operate with the BBC Microcomputer
System Teletext Adaptor (both the Acorn system and the new GIS adaptor)
and ATS or ATS+ software. They are not guaranteed to function correctly on
other makes of adaptor, even with ATS. This is because some other teletext
adaptors use less versatile teletext reception chips, and it is not
possible to implement multiple simultaneous page grabbers. This is a
restriction of the hardware, and cannot be overcome in software.
