The day the Monster stack tournament started there were a number of tournament regular pros tweeting that the Monster stack format favors the pros over amateurs. The general position was that the amateurs were deluding themselves into thinking the extra chips gave them a better opportunity to win. I have analyzed the final 62 players lifetime tournament performance based on Hendonmob database and the WSOP database. My observation is that if this format favors the pros then they need to learn how to play deep stacks because they did not fare very well in the particular tournament. This is especially true when compared to most WSOP tournaments this year that saw a large number of repeat bracelet winners along with very strong final table participants.

Here's some stats of the final 62 players. These are for live events. I didn't research online performance.

2-WSOP bracelets total, only one of which was in an open event. Sean Drake Day 4 chip leader won the employee event. Jason Duval number 9 in chips was a winner of an open event.

132-WSOP combined cashes. 3 players account for 47 of those cashes. 

1-Player with earnings greater then $1 million-Joseph McKeehen who was barely over.

8-Players with earnings greater then $500,000 including Joseph.

37-Players with less then $100,000 career tournament winnings.

30-Players who are making their first ever WSOP cash.

10-Players who are making their first ever live tournament cash.

Granted one tournament does not make for a great sample, however this format clearly favored amateurs the first time it was run by the WSOP. I'm sure the pros will make the needed adjustments in the future. However, it definitely is a little bit early to be saying "the sky is falling" on the amateurs.
