How would your bets yield different results than mine? 
There is nothing random in this, anyone following this strategy will get the same results. When a horse wins, it wins for everybody when it loses it does so for everyone. This is not coin tossing when one gets heads and one tails in the same round.

Tiny update with no copy-pasting the whole thing
- No 5 chains lost either this weekend
- very slow days, so little racing that it was boring (Sunday had only 2 tracks)
- also a reminder, this experiment runs on an available chain of 5 races, so if there are only 3 favorites left I don't take a bet at all, that's why on Sunday I only had 1 bet (at least it won).
