So say I play 50k hands and win at 4bb/100 with a sd of 85bb/100, between what 2 numbers can I say that my actual winrate lies with say 90% confidence, or 80% confidence?
Am I right in saying that this calculator...

will not be able to do this? Or can it?
For example when I type in 50k hands, 4bb/100, sd of 85bb/100 and 90% confidence in that calculator it comes up with -2.25bb/100 and + 10.25bb/100. Now, does this mean that IF my true winrate is 4bb/100 I can be 90% confident that my results after 50k hands will be between -2.25 to +10.25bb/100. Or does it mean that IF I play 50k hands and win at 4bb/100 there is a 90% chance that my true winrate lies between -2.25 and +10.25bb/100?
