Playing multiple tables reduces variance if you are getting your money is an a 75-25 favorite 4 times as much. However, if your getting it in as a 25-75 underdog, its going to reduce the variance of you winning money and therefore you will lose more faster.
This isn't an issue of variance. The issue here is that you're a losing player. Your hourly rate will be magnified by four times if you're playing 4 times as many tables and 4 times as many hands, but your per-hand rate should stay the same (assuming you're not overtaxing yourself with the additional tables). If you're losing a dollar a hand, you'll still lose a dollar a hand when you play 4 tables instead of one, you'll just lose 400 dollars an hour instead of 100 dollars. This is NOT variance; this is just the correlation between volume and profit (loss).

HE is nobody. He offers very little of value, and does not have a mustache.
Also, he's a faggot.

No. A little bird tells me he's currently reading a poker forum in the computer lab instead of attending an environmental science lab. He is also going to get a B- in an Online Intro to Theatre class.
He's a faggot.

No, I was actually about 99% wrong. I just wasn't thinking about things properly. Zach and Tactical Bear are right.
Actually, I feel this point is very valid. Your per hand variance never changes regardless of how many tables you play. Your absolute variance however should be a bit higher becuase of the increased amount of money in play. I'm not talking long term, but I'm talking in any given hour or day, playing 4 tables, you can win or lose a larger amount of money simply as a product of having more money in play. I have to have the ability to win or lose more money becuase I have $800 (4-$200 NL tables) in play as opposed to $200.
If you're in capable of losing 5 buyins in an hour at one table, but it can happen if you're 4-tabling, then I'm pretty sure my above statement has to be true. It's totally short run, but I am quite certain that few people will argue that you need a slightly larger bankroll to play 4 tables at once than you do to play one.
You're still thinking about things wrong.
You can win or lose larger amounts of money playing 4 tables for 3 hours than you can playing 1 table for 3 hours. But you can also win or lose larger amounts of money playing 1 table for 12 hours than you can playing 1 table for 3 hours. Do you need a larger bankroll if you plan on playing more hours/week? Because that's all multi-tabling is. It's just time-compression.
Think about it this way. Say you play 250 hands at each of 4 tables. You take 10 horrendous beats over the course of the 5 hour session, and end up dropping 5 buyins. You play perfect otherwise.
The next day, your friend plays the exact same 1000 hands, except he plays them at one table over the course of 20 hours. He plays exactly the same as you, and takes the very same 10 awful beats from the same players in the same situation, and drops 5 buyins.
Can we really say that because your hands took place in a shorter absolute time-frame you need a larger bankroll than him? Absolutely NOT. If we look at variance in terms of Risk of Ruin -- the only thing that really matters for poker players as far as bankroll considerations go -- then time is of absolutely no importance. It's simply about the expected return for each meaningful unit of contest: in this case, each hand. The math simply doesn't care how long it takes you to get 100K hands in. It just cares about your per/hand winrate, and the number of hands you played. That's all.
Don't think of it like: "I have more money in play," because that's misleading if you're a winning player. The amount of money you have in play will affect your HOURLY return, but not your PER HAND return.
And that's all that matters.

PS- The only argument you can make for increasing your bankroll because you multitable is one in which you stipulate that your winrate decreases as you add tables. Each table may add to your hourly rate, but decrease your per hand rate. Then, it takes less awful luck to bust us, so we need a slightly higher bankroll. For people that multitable, however, this is rarely a concern. My winrate for full-ring LHE went from 3.6BB/100 at one table to 3.3BB/100 when I played 4 tables. 300BB was more than enough at each level.
