What is more important? ROI or overall profit when creating a system with some constant variables but another variable can be used to fine tune it (eg. racetype).

Here are the results of a system, that I have used to create 4 new systems by fine tuning it. The main variables are consistent throughout except I have looked at how it performs when filtering the race type and race category.


System 1 is the version that I am currently using. Would I be better off switching to System 4 as it has produce more overall profit with the same SR and only a drop of 4% ROI?

All profits are to a 1 level stake.
