Re: Does Multi-tabling increase variance?
[ QUOTE ]
anyway you look at it, multi-tabling reduces variance over TIME.
obviously, the more hands you play in a given time unit, the lower your variance will be.

No, that's not obvious. It's wrong by the usual definitions. You must be using a nonstandard definition of variance.
If you bet $1 on a fair coin-toss, the variance is 1. If you bet $1 each on 10 independent coin-tosses, the variance is 10. If you bet a total of $1, evenly spread out on 10 independent coin-tosses, the variance is 0.1. The standard deviation is the square root of the variance, and it tells you the scale of typical results. Sqrt(10)~3, so after betting $1 10 times, typical results would be to win or lose about $3. The swings are much greater than if you only bet once.
To reduce your variance per hour while multitabling, you need to play at lower limits.
