I made a post a while back about the current validity of such spreadsheets and I was "assured" they are correct. (even though they are not)
So, to sum it up, as a general note, I think everyone should be following their respective VO spreadsheet for stage 2.....it means more anyway. Do I really care how fast or slow other VO are going, not really...(I mean, I wish everyone speedy processing, but for analytical purposes).
In the end it screws up the averages and processing analysis to try to outline a trend anyway, so use your VO sheets.
Cheers!
