Do you feel your game improves a lot playing many tables of FR?

[flytrap]

I was playing my usual 4 tables of $200NL FR on Full tilt last night/this morning, and something happened that got me to thinking. I won a 200bb pot off a regular that tried to make a move on me, and instead of doing the normal thing which was just take the pot and keep playing, I started trash talking. Eventually we were sparring back and forth, and he critisized me for only playing 4 tables. I explained that I make 4bb/100 doing this, and we ended up actually having a pretty civil conversation about stakes, numbers of tables, etc. This got me to thinking. Perhaps I could play more and be more profitable. Putting profitablity aside for a moment, what number of tables do you feel is optimal for improving your game? I can see the advantage of playing a lot since you can get more hands in, see many different situations, etc, but the drawback is you don't get to analyze your own play as much, you don't learn to read the other's players as well, and you don't spend as much time on each hand while it is being played. Let's say for a minute that my only motivation was to get better. What do you feel is the optimal number of tables? 1? 12? Somewhere in between?
