playing MTT's over the next year

I'm going to play some online MTT tournaments every day over the next year.
I'm planning on playing the Big 7.50 8k on stars 5 days a week and the sunday storm $11 on sundays. So that's six tournments a week i will play.
I will also play a $11 sat to the big $109 once a week. if i win the sat i will play the $109. this works out to me playing 365 tournments in the next year at the min and maybe playing a few more if i win the sat into the big $109.

is it realistic for a player to win 100% Roi over a 350-400 game sample?

I don't know why you wouldn't play smaller buy in MTTs and just more of them then one a day, this is better as it is bigger sample size, you have more buy ins this way and you can take some days off when you aren't feeling it.
