With regard to many sessions, you can be profitable, but in the medium and long term, you should dedicate more time to achieving goals and results, poker is a dedication to study and grind, if you only play on weekends, you certainly won't study just to play because how You only have time on weekends, I believe your energy goes to the grind, and we know that results come from long work in the area you want to commit to.
EX there are players who play only series but they do a job in that time they are always perfecting the game so when the series arrive they have good results. a series two practically 1 month of games every day.
In my point of view, you will not be profitable in mtts.
Tip: deposit your time on weekends in sit go and set game goals 500 games on weekends will certainly have satisfactory results and study.
hourly load for sitgo friday to sunday min 30 hrs playing 9max, 6max will surely get results!! glgl
