Forum:How does rate of fire impact VATS?

Say I have a weapon that costs 10 AP per shot and I can mod it to increase its rate of fire by 10%. Does this mean I will essentially get the same result per shot by spending only 9 AP (10 AP - 10%)?

No, it just means the next shot will come out of the weapon 10% faster than it otherwise would have. Rate of Fire is how fast a weapon shoots, it doesn't affect the AP cost.

____ Yes, the action point cost decreases. because of the way math wrath & fast shot interact with AP costs (each calculated serially instead of being added together) the synergy with the weapon mod and these may result in less than 10% reduction in AP costs being observed. By serially I mean the AP cost is calculated for one, then the new AP cost for the the second perk/trait/mod is calculated based upon that reduced cost, then the final AP cost is recalculated based upon a percentage reduction of that AP cost.
 * base cost 10 AP
 * 10% reduction from weapon mod = 9 AP
 * 20% reduction for fast shot trait = 7.2 AP
 * 10% reduction for math wrath perk = 6.68 AP
