Double-posting for some critical results. I'm talking about Critical Hits. :)
Okay, first, a summary:
1) High-critical hit moves lose in this generation.
2) Focus Energy gains in this generation.
3) The percentages for CHs seem to be the same as in previous generations, but further testing is needed to confirm this.
Here are all the test results so far. This was done by me and Peterko, by the way. Peterko did most of these, all of them but 2, to be exact, so kudos to him and his patience. :)
Normal moves (no items, no abilities, no high-CH moves, nothing): 3/25, 1/25, 3/25, 0/25 = 7/100 (7%)
Night Slash (a high CH move): 2/24, 3/24, 1/24, 4/24, 2/24 = 12/120 (10%)
Razor Claw with normal moves: 8/104, 14/104 = 22/208 (10.58%)
Super Luck with normal moves: 5/56, 4/32, 4/32 = 13/120 (10.83%)
Scope Lens with normal moves: 5/32, 5/32, 4/32, 3/32 = 17/128 (13.3%)
Focus Energy with normal moves: 6/20, 5/20, 3/20, 4/20, 8/20 = 26/100 (26%)
Scope Lens + Shadow Claw (a high CH move): 4/24, 5/24, 5/24, 7/24, 4/24 = 25/120 (20.83%)
Super Luck + Scope Lens with normal moves: 11/56, 21/56, 21/56, 7/32, 9/32, 9/32, 15/32 = 93/296 (31.4%)
Super Luck + Night Slash (a high CH move): 5/24, 6/24, 4/24, 12/24, 5/24 = 32/120 (26.67%)
Super Luck + Scope Lens + Night Slash (a high CH move): 5/24, 5/24, 7/24, 8/24, 10/24, 8/24, 7/24, 8/24 = 58/192 (30.2%)
Possible interpretation of results (but requires more testing)
There are at least 4 percentages for Critical Hits. I like to call them Critical Hit Domains:
Domain 0: 6.25%
Domain 1: 12.5%
Domain 2: 25%
Domain 3: 33%
Domain 4: ??? (we seem to have never reached this in our tests. This was 50% in previous generations.)
Moves that do not have a high CH ratio are at Domain 0.
High CH ratio moves are at Domain 1. This is different from the previous generations, since they used to start at Domain 2 there. So High CH ratio moves have a 12.5% chance of a Critical Hit, not 25%.
Scope Lens, Razor Claw and Super Luck increase the CH Domain by 1.
Focus Energy increases the CH Domain by 2. This is different from the previous generations, since there, it used to increase the CH Domain by only 1. So Focus Energy + normal move has a 25% chance of a Critical Hit, not 12.5%.
Comparing this to the results:
Normal moves: Domain 0: 6.25% (test result: 7%)
High CH moves: Domain 0 + 1: 12.5% (test result: 10%)
Razor Claw: Domain 0 + 1: 12.5% (test result: 10.58%)
Super Luck: Domain 0 + 1: 12.5% (test result: 10.83%)
Scope Lens: Domain 0 + 1: 12.5% (test result: 13.3%)
Focus Energy: Domain 0 + 2: 25% (test result: 26%)
Scope Lens + high CH moves: Domain 0 + 1 + 1: 25% (test result: 20.83%)
Super Luck + Scope Lens: Domain 0 + 1 + 1: 25% (test result: 31.4%)
Super Luck + high CH moves: Domain 0 + 1 + 1: 25% (test result: 26.67%)
Super Luck + Scope Lens + high CH moves: Domain 0 + 1 + 1 + 1: 33% (test result: 30.2%)
Only Super Luck + Scope Lens seems to vary from the test result, but this might be because of a quirk in the random number generation. If anyone else would like to add tests to this, he or she is more than welcome.
EDIT: Peterko: hmm I miss a sentence: HELP US BY PROVIDING AT LEAST SAMPLES OF 100 HITS FROM ONE OF THESE POSSIBLE COMBINATIONS :D
