XP95 shaft

The standard steel shaft for the new 714 AP1 is True Temper's XP 95.  Titleist lists the weight of the R300 XP95 shaft as being 99 grams. True Temper's web site lists the weight of the XP95 R300 at 93 grams. Is Titleist using a modified version of the XP 95? If not, why the difference? 

We use the exact same shaft - True Temper lists the cut weight and we list the raw weight.
