Theoretical spreadsheet data means nothing to me. Every equation out there is a cooked up, reverse engineered estimate attempting to force a linear scope, assume coefficients, and guess at order or operation placement.
My calculator isn't a spreadsheet. It doesn't guess at anything, it deals in damage multipliers only, where things like order of operations are irrelevant. (For physical, it only compares 2 stats: BP Dmg against Pet:Multi. For magical, it only compares 2 as well: BP Dmg against Pet:MAB.)
That means you still have to take it with a grain of salt because it ignores pet:acc/atk/str/etc. You just have to decide for yourself how to weight the comparison for any changes in pet:acc/atk or enemy eva/def/etc. But it also means there's no guesswork, the comparison should be accurate and if you find it not to be, please let me know.
With AM3 you're going to multi hit anyways.
Assuming you're using Incarnation Sash, Shulmanu, and path D slacks, and with Nirvana AM3 up, your chances of having 5 swings (24%) are still worse than your chances of having only 3 (30%). Most of your Volts (46%) will be 4 swings.
what about Enticer's Pants vs apogee leg +1?
Merit BPs with 1500+ TP (including bonus TP from merits): Apogee+1[A]
Merit BPs with less than 1500: Enticers
Impact, Conflag Strike, Level ? Holy, Lunar Bay: Enticers
Other magic BPs like Thunderspark: Apogee+1[A]
Multi-hit physical BPs: Apogee+1[D]
Single-hit physical BPs: Enticers
