I'm expecting 30 from their top 3. Heep's normally has one good ride at least, so say 5 in total. Need to check what JJ did at Poole last season, must have been okay as Redcar weren't that bad at WR last season. So say 5 as well. So 41 in total.
You know how good I am at predicting though
Edit - 4+1 both times for JJ last season. Once riding at 4 and the other at 7. The time at 7 would have been when the track was really wet though.
So 5 about right.
