Vac gauge

Just installed my vac gauge let me tell you my readings and see if it sounds right. At idle in gear about 20inchs at WOT about 1-2inches at 45mph about 25 inches. Does this sound right? Also my carb has a 6.5inch power valve does this sound right or should I move up to a higher one?

Thanks
