hi GoalScorer
don not worry about to many variables as there is no way that betfair would know how many variables you use.
as for the betfair historical data, they are only interested IF you start monitoring every market from about 12 hours before the start time through to the actual finnish.
a few punters accounts have been closed due to this, because they monitored football matches for a long period through to the finnish,but when they explianed there system, betfair re-opned there accounts.
