Whenever you see the word Bonus, it always has to be cleared. I apologies for not mentioning that. I just always thought it was a given.
However, Iron Man is an on going promotion. If you are just shooting for Iron Man once every other month or so, you are shooting yourself in the foot.
The Iron Man builds on it self, and the more months in a row you hit Iron Man, the quicker you earn medals which means you can purchase bonuses and tournament tickets at a faster rate.
If you are doing Iron Man every month, clearing the bonus isn't a big deal. You are just earning points that you would normally earn. Yeah, the month I'm clearing the bonus, I might ramp up my play a little bit to clear the bonus quicker. However, I received a $450 bonus and the pacing was just 200 points a day for 45 days to unlock it. So yeah, Iron Man is kinda geared for higher limits. Really 25nl imo. Once you are playing 25nl, you can earn 200 points a day in two hours or less easy, depending on how many tables you play.
The Iron Man is intended for people that grind, and over the long haul. This month is almost over, however here is the screen shot of my calender and bonus.
