Variance contributors in NL...

[DcifrThs]

Im curious as to the determinants of the reduced variance in NL.

so far ive come up with the following:

1) fewer players per pot on average (hands hold up more, grouping etc.)

2) fewer turns/rivers/showdowns seen.

3) worse odds to draw so the above is fulfilled

ANd here are some things that negatively contribute to the reduction in variance:

1) bet size on average/hand

2) cost of 2nd best hands

3) more hands played in position that limit

any thoughts or additional contributions?

thanks
