Thanks jcl.

a) I don't understand what you mean by "highest likeliness"? If the CR is what I start with, it's 100% likely , and the return should be based on it.

c) If a system is started with CR and it's lost, that's margin call, isn't it?

e) If my Risk tolerance is 20%, I don't want to lose more than 20%. Therefore, I don't want my account going below 80% CR. How likely is <80%CR? Is there a probability curve for drawdown as a % of CR? Linear? S?
