hi
you would need recording triggers for every racecourse about 87 uk and ire.
also do you realise that if this race is delayed for 5 mins due to a horse playing up, it means that the next race would have a recorded delay of 5 mins and most likely you would miss the start.
even though races are delayed, they always try and get the times back in line, so i think that this idea would miss more race starts than it is worth.
the idea sounds good, it would be perfect if we could get betfair to give a line up/entering stalls message.
for a variable to carry from one market to the next, you just use global
