22B <--- Hold that B, then immediately tap another.
It's 4 Hits after that, the timing is 1 1-2 1. The 1 2 part is only marginally closer input wise than the 1's on the sides. If it was out of a sixty seconds, the inputs would look something like:
1 second - 22B Hold
5 seconds - B
20 seconds - First JF B
35 seconds - Second JF B
45 seconds - Third JF B
60 seconds - Fourth JF B
Then the auto-last hit.
This is a subjective, and non-true ratio to give you a rough idea.
All the B's you press must be clean. For instance If I press 22BBBB during the first hit and THEN time the just frames perfectly, it still wont come out. On that note just practice the 22B hold, B B until you get the flash, THEN start working on the others.
By the time you land your first one you'll get 2-3 in a row. After that, sink an hour or two and you wont miss it, even online.
Every time I do it, I run a mantra in my head (I very rarely miss it,)
"22BeeeBee, Bee Be-Be Bee" Yes... Bee, Baby, Bee.
Call me crazy, but we all have our own shit for these just frames. It always sounds retarded telling someone else.
