[Indev 0.53.2] Iron Tail accuracy

[Ryous]

After a few attempts at using Iron Tail on wild pokemons (during online mode) I noticed the hit rate was awfuly low. Don't take my words on it since I have no proper way to back up my theory, but at this point I believe a move that has supposedly ~75% accuracy shouldn't fail twelve times consecutively, even by lack of luck or circumstances. It might be wise to check the accuracy of the move just for safety reasons.

Move used during the test; Iron Tail
Pokémon used for the test; Aggron. [Special Ability; Heavy Metal]
Opponent pokémon used for the test; Golbats, Gravelers and such...
Area test has been run in; Victory Road

Iron Tail constantly missing? I don't know, that doesn't seem all that out of the ordinary to me.

Did you try giving it a hold item like a Zoom Lens to see if it improved the accuracy?

Test run with; Aggron [Heavy Metal] using Iron Tail (75% accuracy) + Zoom Lens (Adds +20% accuracy)

Theorical Hit-chance ratio; 95
Effective Hit-chance ratio based on test average; 75
Supposed real Hit-chance ratio without Zoom Lens; 55

The issue here isn't that Iron Tail is an inaccurate move. It's that from the looks of it, it's way more innaccurate than it should be.

The issue here isn't that Iron Tail is an inaccurate move. It's that from the looks of it, it's way more innaccurate than it should be.

20% increase to 75% is not 95%, it's actually 90% and that increase only happens if your Pokemon moves second in the battle.
Also, you could miss all 100 tries and still won't make the move any less accurate, it just means that you're super unlucky.

The code for Iron Tail appears fine, dismissing as incredible unluckiness.
