My club distances for the Nike Vapors (L96) have changed by as much as 2%-8% in yardages. I know this because I calibrated my clubs before and after the Feb. 1st update, under the exact same conditions. Why would WGT change the club specifications?, or have you changed the dynamics of the courses to be inconsistent with elevation and displayed wind speeds? There are a lot of players out here who have noticed the change. You really can't be that desperate for cash, by increasing the number of balls hit per round, are you?
