Hi,
something's up with Technician + type specific attack boosting items such as Silk Scarf in DPP. Life Orb calcs are just fine, however.
All of the following calcs were done with a Technician Scizor (even those that do not show Technician):
DPP
252+ Atk
Insect Plate Scizor Bug Bite vs. 252 HP / 252+ Def Blissey: 235-277 (32.9 - 38.7%) -- 99.5% chance to 3HKO
and
252+ Atk
Life Orb Technician Scizor Bug Bite vs. 252 HP / 252+ Def Blissey: 382-450 (53.5 - 63%) -- guaranteed 2HKO
BW
252+ Atk
Insect Plate Technician Scizor Bug Bite vs. 252 HP / 252+ Def Blissey: 351-414 (49.1 - 57.9%) -- 97.7% chance to 2HKO
and
252+ Atk
Life Orb Technician Scizor Bug Bite vs. 252 HP / 252+ Def Blissey: 382-450 (53.5 - 63%) -- guaranteed 2HKO
Oddly enough, this only appears to affect moves with a flat 60 BP. Metal Claw has 55 BP and gets both boosts (as it should):
DPP
252+ Atk
Metal Coat Technician Scizor Metal Claw vs. 252 HP / 252+ Def Blissey: 294-346 (41.1 - 48.4%) -- guaranteed 3HKO
BW
252+ Atk
Metal Coat Technician Scizor Metal Claw vs. 252 HP / 252+ Def Blissey: 294-346 (41.1 - 48.4%) -- guaranteed 3HKO
STAB doesn't seem to be the root of this error:
DPP
252+ Atk
Sharp Beak Scizor Wing Attack vs. 252 HP / 252+ Def Blissey: 157-185 (21.9 - 25.9%) -- 3.6% chance to 4HKO
BW
252+ Atk
Sharp Beak Technician Scizor Wing Attack vs. 252 HP / 252+ Def Blissey: 234-276 (32.7 - 38.6%) -- 99.3% chance to 3HKO
I didn't find anything online that suggests Technician works differently in DPP and the discrepancy between Insect Plate Bug Bite and Metal Coat Metal Claw (which both increase the power to above 60 BP with the help of the respective type specific boosting item) leads me to believe that this is an error. PS doesn't have this issue either; Insect Plate + Technician boost Bug Bite to the correct power of 108 in DPP games as intended.

I appreciate any help, thanks!
