Hi Derek,
I don't think the number 3.8 was put into the sample sheets following a great deal of empirical testing. It was probably just there to demonstrate a number that seemed sensible, then for users to test and adjust according to their own appetite for risk / reward.
You are correct to say that the lower that number is, the less races you'll have in which any bets will be triggered, but the greater chance those bets will have of at least two horses being successfully matched.
Kind regards,
Gavin
