Whoah, thanks it's a great help!

But I still have one question: If I get it right, I can calculate an interval for my ROI based on my observed ROI of a certain amount of SnGs.

However, I somehow feel that if thats interval is somewhat like -10% and +50% (for example), then the edges of the intervals have less chance to be true than the middle. Is this right?

(sorry for the crappy phrasing, so, to make it clear: in the given example, Hero has more chances of having the middle of the interval (+20%) as ROI, than either the -10% or the +50%. So is there any easy way to caclulate the possibilites of certain ROIs?

I'm sorry if this was somehow implemented in your previous post, I'm not an expert of the subject

)

And thanks again
