The strike rate would be less but dividends would be better.

As I write this, 39 greyhound races so far today. 1,2,7,8 have won 26 races (67%) for a return of $106.90, and 3,4,5,6 have won 13 races (33%) for a return of $121. Meanwhile 1,2,3,4 have won 25 races (64%) for a return of $130.70. Interesting. Looks like you could be on the right track Dingoboy.
