Shai, look at live only. Online SDev is much lower, as went to showdown rates are so much lower. In live you are much more often at the mercy of the deck. bip! has a great discussion of SDev ITT from (IIRC) 2016, that is worth searching out. And just like winnings, hourly rates are much more common in live, and per 100 hands rates in online.

Richard32, your low SDev shows that you are likely passing up on a lot of +EV spots, because if you were taking them, sometimes your Vs would suck out and create bigger swings, but overall you'd win more.

I have a 5.2 bb/Hr winrate after 325 hours of 1/2 and 2/5

My SD (in bb/Hr) is 50.

What does that tell us?

Absolutely nothing cause it's a mini sample size, gotta go grind....

Okay but you are saying the standard deviations from live are around 200BB/100 whereas online people most commonly say 80BB/100, which means live variance is (200/80)^2 = 6.25 ~ SIX times as bad? I can see how it may be worse, particularly when buying in 200BB deep vs 100BB deep as online, but it can't be that much worse. Surely? I am struggling to imagine how I could even get a SD that large. The LAGgiest winner in my room (that I know of) has 147BB/100 or 80ishBB/hr. I'll try to find these posts from Bip!

The problem with hourly standard deviation rates is statistically it's just an approximation for BB/(hands dealt per hour). It is imprecise and leads to inconsistencies like you see with GG's session SD vs. hourly SD.

@stlows - standard deviation converges much faster than winrate, I think after 325 hours it is likely fairly close to your true SD.

EDIT: Found the post you were referring to Garick. I think it's this one

Bip! says 60 - 70 BB/hr which is ~110 to 127 BB/100. If I average at 118BB/100 and take online average at 80BB/100 then variance is 2.17 times as bad live. This seems a lot more believable to me.

I actually meant the discussion that starts here. The chart is no longer live, unfortunately, but it led to a lot of folks figuring and then reporting their SDevs and 95% confidence intervals of WR. At the time, mine was the lowest SDev ( ) in the thread, and I think bip! (who was very laggy and later switched to PLO) was somewhere in the 140BB/hr range. IIRC, most folks ITT fell in the 70-100 hour range.

I play mainly 1/2.

575h since april , 22,93€/h
SD 118,67/h

What does my SD tell us?
Is it normal?

Do you mean too nitty preflop, post flop or both?

Suyupa, it's a bit on the high side for a winning player, but not outrageously so. Sounds like you play in a pretty wild game.

Gravity Well, it's hard to tell just from SDev if Richard32's nittiness is more pre or post, though pre tends to have the greatest effect on SDev. Still, with an SDev that low, I suspect both. It looks like he might be playing a bit weak/tight.

Posting hands and getting flamed will say much more about your game than winrate SD imo. Seems like SD says just as much about game conditions as it does about your own play.

It depends but most of the time people dont fold much pre and dont like to fold postflop which makes variance higher. So i think it could be because of (bloated) pots always being multiway where you have to give up a lot when not hitting good enough.

Or what do you think could be the reason?
Im not playing overly aggressive.
Most of the time the players are also not very aggressive.

What is a normal SD in bb?

I feel far too spewy at times and my SD is only 162/hr with 90 percent of that at 1/3

Personally, I wouldn't be too concerned about your SD, but that's me. I also wouldn't be too concerned about any style you're playing so long as you think it's a decent one for your game and you're winning. Changing your game just to satisfy a SD or "TAG" or whatever requirement is meh if what you're doing is working in your conditions, imo.

Lately during my Super Nit method I've been rocking an almost 0% raising range from anything up to (and even sometimes including) CO/Button, the very definition of "weak tight". Rocking a 7.9 bb/hr winrate this year using this method (yes, I had a good session yesterday to bump it up a bit). Do what works, and be suspect of people telling you otherwise (especially if they're not backing up what they're saying).

Thought I was the only one that DGAF about SD. It’s a dependent variable. Who cares.

Its not that im looking every day at my SD but just would be interesting to know the meaningfulness of SD about the own game.

And at what point is SD bb/h too low or too high?

Really, aside from giving a hint about how you play, the only effect of SD is that higher ones have greater swings, which means a higher risk-of-ruin if playing under-rolled and a wider confidence interval between observed results and "true" winrate.

There's nothing inherently bad about that, though.

Not raising preflop has nothing to do with being weak tight.

Aight thx

how does one import an image without having to provide a url?

One does not.

You have to upload your image to the internet in order to display it here, I'm afraid.

LOL, so maybe upload to google docs? Will that work?

I usually use tinypic.com.

After 440 hours of play at mostly 1-2 NL:

Profit of 9.3BB per hour


SD of 83 BB per hour

I have no idea what that's telling me, since I don't exactly know what standard deviation is...…….

Can anyone comment on the above stats are these healthy numbers? I seem to be hitting a plateau i need to break but i'm very concerned about the future here I need to break past this 3k mark. I have some leaks in my game that I never buyin for more than $150 and constantly playing short stacked.

Cold deck for me recently with hands like AK vs AQ KQ ver K8. all in pre some bad beats and the occasional bad plays which fortunately for me aren't too expensive and often.

$69 per session....nice.

Looks like you generally lose. Which means your wins are quite large. Normally not a recipe for success.

Short stacking is not my forte. But I would start to post a few hands. See if you can find leaks. With 30% win rate I doubt your a longterm winner.

Read the last 25 posts or so. We've been discussing it. Your SD is right in the normal range of what folks report ITT. Not hugely swingy or particularly nitty.
