Ok, I couldn't edit the other posts to fix up the results but here are the overall stats :

System 1:
Races:25
Wins:8
Win $:39.40
Places:16
Place $:30.60

System 2:
Races:26
Wins:2
Win $:18.20
Places:10
Place $:18.80

System 3:
Races:7
Wins:2
Win $:19.00
Places:6
Place $:13.20

Overall it appears that System 1 (fastest split times) and System 3 (large margin) seem to be both in profit. I will probably drop system 2 as it is too inconsistent.

I'll try to post tommorrows tips a bit earlier.
