I have some (not very recent) Twidlit statistics giving:
Left hand
00LM 1095ms (123) 52nd overall
0RMM 1246ms (361) 84th overall
Right hand
0RMM 1182ms (150) 98th overall
00LM 1315ms (330) 127th overall
That's averaged over 16 presses mixed in with random other chords. The value in parentheses is the range of variation. My left hand still is nowhere near as good as my right.
Thumbless has them as
0RMM = <Ctrl><Shift>m
00LM = <Ctrl><Shift>i
because 000M is <Ctrl><Shift>
