I'm probably one of the few NMA readers who puts weekly YFF data into a spreadsheet for analysis. I find it extremely useful for spotting trends and tendencies, and for choosing players who are most likely to help my team, either as big scorers or enablers.
While I've been collecting the data from the YFF site myself I also refer to Data Head's Google Docs pages, and am amazed that he was entering the data by hand (a lot of time and effort to be sure). When I went back to DH's page to get game stats for Spurs' and Everton's double game weeks I saw that the data seems to have ended at Week 15. Did DH stop at that point or are the columns for Weeks 16 and on hidden? The other spreadsheet showing team point totals appears to be complete.
Also, since I have a way to collect most of the player data that's nearly automatic, I'd like to help this effort as much as possible if there's enough interest. It's a great way to test your theories and find ones that actually work.
