Hi there!

So I made this little excel-spreadsheat that can give you a range to estimate your "true" bb/100. So if you are for example a winning player over x hands this tool can tell you how confident you can be that you are really a winning player in the long run and not just on some sort of upswing. (The same goes for downswings of course).
What you get is something like "with x% your bb/100 is between y and z".

This might be useful for people who already know the math behind confidence intervals and just want a template so they don’t have to fill in the equations into excel every time they want to compute it. But I hope this is also useful for people who do not know much about statistics but still want to have an estimation of their bb/100.

I attached a little tutorial that should make clear how to use this even for people who don't know much about statistics.

Any suggestions on how to improve this thing (anything from correcting my bad English to issues about the statistical testing) are greatly appreciated!
