The best non-auto-catch ball btw is Level ball, it tops out at 8x Catch rate if your level is 4 times+ that of what you are trying to catch, but that's only possible up to level 25 pokemon. --- Pokemon Black 2 FC: 5372-8212-5739 3DS Friend Code 0430-8284-1167
I think the official guide books are where that came from. Serebii's old DP item list says it decreases every five turns, as well. --- http://i.imgur.com/rbBq9.jpg Come to the board in my quote for math discussion and pretty much anything else.
They are pretty nifty I agree, but I feel I should tell you something about levels; A level 1 and a level 100 of the same pogeyman have the same exact chance of being caught.
That's not necessarily true. At any given amount of HP less than the maximum, higher-level Pokémon are actually easier to catch than they would be at lower levels since the current-to-maximum HP ratio is lower.
EDIT: Just remembered you were talking about Quick Balls; assuming you threw one on the first turn, it would be the same chance since it would have max HP anyway... --- FC: 4084-3347-5517
