In general, Bonus money is not ROI money.

For your own personal stats, it really doesn't matter what you record as included in your ROI. It only really matters when you want to do things like compare your results to those of others. Or to compare your stats to what you think is attainable. Adding bonus money to your ROI will artificially increase your ROI over what it "really" is. That's why people don't include bonuses or rakeback in their ROI calculations.

In the long run though, there are 3 categories, right? Negative money, 0 money, and + money, to paraphrase Yugo. All that "really" matters is to try to be in the last group.
