01:32:156 (92156|3,92156|2,92156|0), 01:39:656 (99656|3,99656|2,99656|0), 01:47:156 (107156|0,107156|1,107156|3), etc... - This doesn't deserve a triple at all imo, there's no sound to emphasize
01:54:891 to 02:00:516 and 02:02:391 to 02:08:016
I think you should double check the gap between this diff and Ultra, since a lot of the patterns used here are more physically straining. This is mainly because you use a lot of [1][2] and [3][4] chords on Ultra which give a break to either hand, while Extra uses primarily two-handed chords so there's less breaks
Also, some spots have more tricky jack usage like 01:56:766 and 01:57:234 where the one-hand / two-hand effect is really apparent
02:20:789 (140789|1,140789|0,140789|2,140906|1,140906|3,140906|2) - I think a better transition would be to use doubles here, since it was just singles previously (ex. 02:20:086 (140086|0,140320|1,140555|2) )
ok made 02:20:789 (140789|0,140789|1,140789|2,140906|1,140906|3,140906|2) - them doubles
04:37:664 also done
04:41:062 (281062|3,281062|2) - How about using the same chord as 04:39:656 (279656|3,279656|0) here?
