The 2+2 Forum Archives: Compiled Small Stakes stats

Introduction:

The intent of this post is NOT to have players change their game in an effort
to make their stats look more like those presented.

This post is intended to give people who are curious about their stats an idea as
to where other winning players stand. The one-half standard deviation range about
the mean is probably a good range for your stats to be in.

It is very likely that winning players exist whose stats fall outside of many
or all of these ranges. Likewise, it is very likely that some losing players
have stats which fall within all of these ranges.

Stats are great for plugging large leaks. If a player has a VPIP of 8.2% or 34.1%,
they clearly are not playing an optimul number of hands. Examining stats will not
take a 1.5BB/100 winner, and turn him/her into a 2.2BB/100 winner. These improvements
need play time and hand posts.

You might be calling the correct pecentage of river bets, but that doesn't tell us
that you are calling the RIGHT rivers.

Preface:

The two most commonly used statistics when measuring a group of data are: mean
and standard variation.

Mean: This is simply the average. You add all the numbers together, and divide
by the total number of observations.

Standard Deviation: This is the measure of spread. I will leave the complicated
formula out of this. Basically, the further the data tends to fall from the mean, the
greater the standard deviation.

For example:

{5,7,9,11,13} and {1,3,9,15,17}

have the same mean: 9, but the second set has a greater standard deviation.

In addition to these two statistics, the following will also be used:

A one-half standard deviation range about the mean: This is a range that measures

from
0.5 standard deviations below the mean to 0.5 standard deviations above the mean.

For example: In a data set with: mean = 10; standard deviation = 6;

This range is: 7 - 13.

Min: Smallest datum in the set.

Max: Largest datum in the set.

Methodology:

I asked for stat submissions from 2/4 and 3/6 players in the small stakes forum.

I received 21 sets of stats from 2/4 players and 10 from 3/6 players.

(This ended up being roughly 504,000 hands for 2/4 and 313,000 for 3/6).

Using S-Plus software, I proceeded to compute the data in the preface.

Thanks:

I owe many thanks to all those who sent me their stats. As some did it anonymously,
I can't name names here. But you know who you are. Thanks!
