Do Heavy Balls in PLA have a higher catch rate on heavier Pokemon?

Question

I don't know if the mechanics are the same.

Comments

Not sure if the tutorializing is complete, but the game is pretty up-front about Heavy Balls (and Leaden Balls, by extension) have a significantly stronger Back Strike than other balls.  There's no mention of the main line's weight mechanics.

Which I find strange.

Answer 1

For now, my own research into this topic has provided an answer I am ok with.

Yes it does.

After playing through the whole game, I decided to test this wherever I could. After doing a couple tests with really heavy Pokemon and the worse versions of the Heavy Balls, (Heavy Ball and Leaden Ball,) I can say that it does impact the catch rate by a lot.

For example, I caught Palkia at half health with one Leaden Ball, (small bounce too,) as well as an overworld Alpha Rhyperior with no food and no back strike, (didn't see the bounce on that one.) These are just the most recent cases.

If somebody can show me evidence one way or another that impacts my answer/question I will gladly take it, but this answer is good enough for me
