I realized that the 913 Performance Fitting Chart has changed from the 910 Chart in one aspect - the dividing line between draw and fade has been moved toward the right (for the right-handed chart).  So, in other words, the standard A1 setting, which used to be described as slightly fade biased, is now slightly draw biased.

Is this the result of more draw bias built into the club heads, or from fitting experience since the 910 chart was published.  

I'm curious!

Thanks!
