It really depends on the limits I play. There are days you play 10+ tournaments at the same time, but a lot of those tournaments are in the $3-$11 buy-in range, which means that they have huge fields. It's pretty hard to reach a final table in those.
If I play a $20 tournament on a secondary site like
888 or GGPoker, then reaching the final table is a lot easier.
In other words, you can't generally say how many final tables you will reach.
