Exactly that, the point stands the higher your EV the higher potential 'under EV' you have.
So while it would be nuts to run 99 below EV, it would not be that unusual to be at 65% EV and run at, say 45%. The closer it gets to even the more you can expect to run below your EV, the higher EV you have the more potential there is to not meet your expectation (though it should be rare).
I have Minitab, so mayhap if I have a few minutes later today I'll make some more sophisticated plots. Though I do love duggs' hand-drawn giraffes itt.
It's not much that its more common more that it's more widely spread, running slightly below EV is less common than running slightly above EV but running way below EV is more common than running way above EV

Just went through the whole thread. Have nothing to add . Just wanted to say that you guys are nuts.OH,, and im never going to sit at a cash table with any of you. taking things to new levels here with this scientific stuff. got us normal people panicking that we are slow.
I don´t get why bigger pot means bigger variance?.The bigger the pot is the bigger the variance will be (within reason, obviously if you get it in with 100% equity all the time in big pots variance is 0).
Does the Central Limit Theorem not apply here?
We flip 100 times for $1, win 80%. Obviously our ev is $80. We win all 100 0.8^100, how often do we win 60? I think as the number of samples gets high enough (what's high enough?) it becomes closer and closer to a normal curve vs. a skewed curve such that it should be pretty equally likely to run above or below ev. I've got other school stuff to do now but when I'm done I might write a quick program to run simulations on this.
Like obviously it will never be a perfect normal distrubution because of the upper bound on how good you can run being a lower distance from the mean than the lower bound but as you have more and more samples there becomes an effective lower bound as going below it begins to be running 20+ standard deviations below the mean which just doesn't happen lol.
I don´t get why bigger pot means bigger variance?.
If in a 50bb pot we are 70% favorite, and in a 200bb pot we are 70% favorite, variance should be the same no matter pot amount. What i missing?
Sure $ difference on ev would be higher with bigger pot but i don´t see why variance should not be the same??
I mean, it's still a binomial distribution, so it's not like it's some vague, unknown distribution where we desperately need to use the central limit theorem. But if it makes you happy
http://en.wikipedia.org/wiki/Binomial_distribution
"If n is large enough, then the skew of the distribution is not too great. In this case a reasonable approximation to B(n, p) is given by the normal distribution
N(np, np(1 - p)),
and this basic approximation can be improved in a simple way by using a suitable continuity correction. The basic approximation generally improves as n increases (at least 20) and is better when p is not near to 0 or 1."
ok yeah I'm dumb but yeah this does show that we should be able to use CLT even for skewed distributions if we have a large enough sample (and generally I'd imagine poker samples are much larger than statistically large enough, which is typically something like 20 or 30).
