The One Sided Rollout is correct.

The wastage is calculated wrongly on the Evaluation. It has (I think):
 PlayersWastage = PlayersEPC - OpponentsPips
 OpponentsWastage = OpponentsEPC - PlayersPips

The Mean Rolls for the classic 7-5-3 (79 pips) distribution differs on the 
Evaluation and One Chequer Race displays.
Evaluation shows Mean = 10.539 and epc = 68.068. This number is correct.
One Chequer Race Mean = 10.006. The epc is calculated from this correctly and 
the wastage follows from this. There is also a small rounding error. Are you 
using 8.167 rather than 49/6? Call me a pedant, but would a few more 6s hurt?
