"Are my Jacks Okay?!?!?!"

[dore]

So yeah, lots of people are always asking "are [insert #] bpm [insert note type] alright?" Here's some cutoff points for you. Note that any bpm in between these cutoff values will have a percentage of jacks of the two values the bpm is bounded by (e.g. 175 bpm 16th jacks will have some 3 framers and some 2 framers since 175 is between 150 and 225, the two cutoff points on either side).

PUT SIMPLY
The max speed you should have of 4th jacks is 450bpm
The max speed you should have of 8th jacks is 225bpm
The max speed you should have of 12th jacks is 150bpm
The max speed you should have of 16th jacks is 112.5bpm
The max speed you should have of 24th jacks is 75bpm
etc.

Any jacks faster than that listed above risks auto-rejection for potential 3-framers. While not all files will be rejected for potential 3-framers, most will be, so unless there is an extremely musically-relevant reason to put in a jack faster than this you will most likely have your file rejected.

============================
Cutoff Values

For 16th notes:
90bpm = 5 framers
112.5bpm = 4 framers
150bpm = 3 framers
225bpm = 2 framers
450bpm = 1 framers
900bpm = 0 framers

From these values, a little simple math can help us determine everything else.

For 4th notes:
360bpm = 5 framers
450bpm = 4 framers
600bpm = 3 framers
900bpm = 2 framers
1800bpm = 1 framers
3600bpm (lol) = 0 framers

For 8th notes:
180bpm = 5 framers
225bpm = 4 framers
300bpm = 3 framers
450bpm = 2 framers
900bpm = 1 framers
1800bpm = 0 framers

For 12th notes:
120bpm = 5 framers
150bpm = 4 framers
200bpm = 3 framers
300bpm = 2 framers
600bpm = 1 framers
1200bpm = 0 framers

For 24th notes:
60bpm = 5 framers
75bpm = 4 framers
100bpm = 3 framers
150bpm = 2 framers
300bpm = 1 framers
600bpm = 0 framers

For 32nd notes:
45bpm = 5 framers
56.25bpm = 4 framers
75bpm = 3 framers
112.5 bpm = 2 framers
225bpm = 1 framers
450bpm = 0 framers

For 48th notes:
30bpm = 5 framers
37.5bpm = 4 framers
50bpm = 3 framers
75bpm = 2 framers
150bpm = 1 framers
300bpm = 0 framers

For 3/32nd notes:
135bpm = 5 framers
168.75bpm = 4 framers
225bpm = 3 framers
337.5bpm = 2 framers
675bpm = 1 framers
1350bpm = 0 framers

And finally, for 64ths:
22.5bpm = 5 framers
28.125bpm = 4 framers
37.5bpm = 3 framers
56.25bpm = 2 framers
112.5bpm = 1 framers
225bpm = 0 framers

5-framers: No overlap at all, you will only avmiss if you hit the first arrow late. Always okay in any file.
4-framers: The last perfect frame will be covered up. You have to hit one of the early frames to get perfects on both arrows. The only way your file will get rejected for 4-framers is if you have 8435843 in a row (like AIM Anthem).
3-framers: 2/3 of the perfect window is covered up. You have to hit extremely early to avoid avmissing while still getting a perfect. Your file will most likely get rejected for 3-framers unless you are stepping an extremely technical classical piece of music.
2-framers: Impossible to AAA, you must hit before the perfect window to avoid an avmiss. Your file will be rejected for 2-framers unless it is a FGO (difficulty 12/12) classical piece, and even then it might not go through. It's best to avoid them altogether.
0/1-framers: Don't waste the judges' time.

I hope this helps everyone.
