this is an odd calc i ran into. not sure if its a bug or not but still odd.
0- SpA Technician Ambipom Grass Knot (80 BP) vs. 252 HP / 4 SpD Quagsire: 292-344 (74.1 - 87.3%) -- guaranteed 2HKO
i tested it and it was an oddity.
https://pokepast.es/2c0619a5abfee221 the sets i used. is this a bug or just an oversite?

Let me do out the Math a bit
(42*80*140)=470,400
Floor(470,400/167)=2,816
Floor(2,816/50)+2=58
58*4=232
The weird part is that if Ambipom has 0 SpA IVs, then that is the lowest damage roll.
0- SpA Technician Ambipom Grass Knot (80 BP) vs. 252 HP / 4 SpD Quagsire: 232-276 (58.8 - 70%) -- guaranteed 2HKO after Leftovers recovery
Possible damage amounts: (232, 236, 240, 240, 244, 248, 248, 252, 256, 256, 260, 264, 264, 268, 272, 276)
Also, it’s very close to being 2/3rds (or un-technician boosted) of what the final damage is
0- SpA Technician Ambipom Grass Knot (80 BP) vs. 252 HP / 4 SpD Quagsire: 292-344 (74.1 - 87.3%) -- guaranteed 2HKO after Leftovers recovery
Possible damage amounts: (292, 292, 296, 300, 304, 308, 312, 316, 316, 320, 324, 328, 332, 336, 340, 344)
Lastly, giving Ambipom another ability gives the correct calculation.
0- SpA Ambipom Grass Knot (80 BP) vs. 252 HP / 4 SpD Quagsire: 196-232 (49.7 - 58.8%) -- 67.6% chance to 2HKO after Leftovers recovery
Possible damage amounts: (196, 196, 200, 204, 204, 208, 208, 212, 212, 216, 220, 220, 224, 224, 228, 232)
So basically the Calculator is incorrectly giving a technician boost to Grass Knot when Ambipom shouldn’t be.
Here is Low Kick as well;
252+ Atk Ambipom Low Kick (80 BP) vs. 252 HP / 252+ Def Quagsire: 64-76 (16.2 - 19.2%) -- possible 8HKO after Leftovers recovery
Possible damage amounts: (64, 65, 66, 66, 67, 68, 69, 69, 70, 71, 72, 72, 73, 74, 75, 76)
252+ Atk Technician Ambipom Low Kick (80 BP) vs. 252 HP / 252+ Def Quagsire: 96-114 (24.3 - 28.9%) -- possible 5HKO after Leftovers recovery
Possible damage amounts: (96, 98, 99, 100, 101, 102, 103, 104, 106, 107, 108, 109, 110, 111, 112, 114)
Same problem. And for control.
0- SpA Ambipom Shadow Ball vs. 252 HP / 4 SpD Quagsire: 49-58 (12.4 - 14.7%) -- possibly the worst move ever
Possible damage amounts: (49, 49, 50, 51, 51, 52, 52, 53, 53, 54, 55, 55, 56, 56, 57, 58)
252+ Atk Ambipom Anchor Shot vs. 252 HP / 252+ Def Quagsire: 32-38 (8.1 - 9.6%) -- possibly the worst move ever
Possible damage amounts: (32, 32, 33, 33, 33, 34, 34, 34, 35, 35, 36, 36, 36, 37, 37, 38)
(255 Base Speed Ambipom)
0- SpA
Technician Ambipom Electro Ball (150 BP) vs. 252 HP / 4 SpD Quagsire: 272-320 (69 - 81.2%) -- guaranteed 2HKO
Possible damage amounts: (272, 274, 278, 280, 284, 288, 290, 294, 296, 300, 304, 306, 310, 312, 316, 320)
(255 Base Speed Quagsire)
252+ Atk
Technician Ambipom Gyro Ball (150 BP) vs. 252 HP / 252+ Def Quagsire: 90-106 (22.8 - 26.9%) -- 36.7% chance to 4HKO
Possible damage amounts: (90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 106)
Lastly is this.
If you change the BP of the moves to 61, the damage calculator works fine.
Clearly this is a problem with Technician using the value in the BP Box instead of the real BP.
