Question

If for the next 360 days I sample 60 greyhound races (6 runners) per day, where I aim to pick a greyhound that loses in each race using a fixed technique, and achieve a mean success rate of 88.34% at the end of the 360 days, would randomly selecting 3 races from 60 per day for the following 360 days (assuming the same end success rate) increase my success rate?
