Accurate but meaningless. Great.

What's the mean and standard deviation of the following:

3 apples
25kg of sewage

If you want to know your risk of ruin for cashgames you need your hourly rate and standard deviation and bankroll without tournaments included.

This won't give you any numbers worth something.

Tournaments and ring games are totally different concearning SD.

It means the deviation of the BANKROLL. Got it?

Dude, let's think about this. You came to these boards asking for help with your game. Maybe perhaps it should enter your mind that someone else might actually know more than you.

Standard deviation is the squareroot of variance, so tourneys and ring games cannot get put together.

Delete the tourneys from your stats, tell us your hourly rate and I tell you your risk of ruin.

That is what matters

Well in this particular case I disagree. Perhaps others on the board should take into account your advice: Perhaps you are not right. It could be possible. I will happily accept your advice as long you provide an ARGUMENT. Saying I know more than you and therefore you should accept everything I say is not helpful.


The deviation of my account is the only thing I'm interested in, because I see it on my bank account. That is the reason why I mix up MTTs, SNGs and Ring. There are probably standard figures for ring games. But you can definitely work out a deviation for mixed games aswell. So any of you who plays MTTs and Ring games could give me your deviation/account figure and then I can compare.

Standard deviation is the squareroot of variance ==> tourneys and ring games cannot get put together

Mmh, I will think of it.

1+1=2 ==> tourneys and ring games cannot get put together

Wow, logic is so easy.

Okay here is an argument to think about.

Say you can compute SD(ring) and SD(mtt). Now why shouldn't it be possible to compute SD(ring+mtt)?

For n games that is: (xi the ith game and X the arithmetic average)

SD = sqrt(1/n(sum([xi - X]^2)))

For n ringgames:

SD(ring) = sqrt(1/n(sum([xi - X]^2)))

For m MTTs:

SD(mtt) = sqrt(1/m(sum([xi - X]^2)))

For n+m ring and MTT games: (yi the ith game of ring and MTT and Y the arihmetic average)

SD(ring+mtt) = sqrt(1/(n+m)(sum([yi - Y]^2)))
