I value where a pitcher sits with his velocity moreso than where he can bring it once in awhile to get a hitter out in a key situation. If Prior throws 70 pitches (55 fastballs), his range probably was 85-91 with 5 probably 90-91 and 5 probably 85-86, with the other 45 87-89. That 87-89 is more important than either side of the spectrum, espec. if he did get 1 or 2 at 93. This is also more important for a starter than a reliever, who's exerting more energy than a starter conserving his for a 110 pitch performance, You can trust a radar gun, but if the reading looks odd compared to what he has previously done, it probably is. If Prior had one at 93 and he was sitting 86-87 with maybe one or two more at 90, I think the 93 would be off. In general, many get too caught up with the gun. I'd rather focus on his deception, life, and command of his FB rather than velo as well as the command and break of his curve.
