Poker Field Trends (Week 2 of Tracking)

Hey guys,
I've started tracking poker field sizes in 28 key high buyin tournaments and have created a system for tracking them. As my data gets more inclusive I plan on adding new stats, and formulas. Right now, the most important statistic I am offering is the change in field sizes between the 5 week moving average and the 10 week moving average (denoted as 10/5 Chg) as well as the first 5/last 5 chg (denoted as F5/L5 Chg) which averages weeks 1-5 and weeks 6-10 and finds the growth trend. Finally, as you see at the bottom is the Poker Field Index, this denotes the overall field trend for these 28 tournaments based on their moving averages. I will be updating this every week and possibly adding more tournaments to track. Right now I am focusing on high buyin tournaments as the satellites to them help to track low buyins in the same breath.

Inside the Numbers
This week we saw the FTOPS come to a close so I am anticipating a lot of contraction in the field sizes this week, especially on FTP, as the FTOPS is known to bloat their field sizes. I will be interested to see how this effects the other sites as well. The PFI stands at a 2.36% growth this week. So from all indications, fields are still growing.
