I am going the opposite way than what others say, lets say you join a 2.20$ 1R+1A and that you TAKE the R+A

You are therefor in a 6$ MTT, with a .20$ Rake.

If you join a 6$ MTT, you will be paying at the minimum .60$ Rake.

Now, put on an individual basis, the .40$ Difference is not huge, however, put it into a 2500 people MTT, that .40$ suddenly becomes an added 1000$ to the prizepool... Which is simply laying there for you to have...

Of course, when buying into a +R tournament, you need to take into condideration that it is no longer a 1.10$ MTT, or a 2.20$ MTT, but now three times that amount.

The idea is to 3x the buy-in amount, so that you can still keep proper Bankroll Management in the EVENTUALITY that you need to rebuy and addon.
