Needs Triage Bug Report - Mechanics

[Cazenovia]

What type of bug are you reporting? Mechanics

What is the bug?
In Gens 3 and 4, if False Swipe does not do any damage to the target (due to the target already being at 1 HP), then King's Rock will never activate and the target will never flinch. This is currently unimplemented on PS!.

Are you able to replicate it? If so, how?
Gen 3 | Gen 4 ((9/10)^63 = ~0.1% chance of not getting a single flinch in 63 False Swipes)

False Swipe can flinch in Gen 2 | Gen 5 | Gen 7

From the decompiled code, I can't tell whether it refers to damage calculated or damage dealt. Can King's Rock cause a Shedinja with a Focus Sash to flinch?
