Per the Wynn Poker Tourney winners site (http://wynnpoker.com/winners.cfm), it looks like most weeks is between 100 and 130. But, I went back through September 2015 and saw a low of 80 and a high of 159, so there is a bit of variation on that.

This month they had
140 on January 16th
96 on January 9th
102 on January 2nd
