    (STM move count here doesn't cancel moves between steps, unlike what I've been doing in most other reconstructions.)

    Here
    I haven't seen one either, although @xyzzy you might want to check the scramble in the video as the scramble Feliks has at the end is not the same one you have listed (likely due to a misscramble).

    Also that was 196 ETM/32.38s=6.05 ETPS

    Oh, trust me, I've spent a lot of time checking the scramble. I'm pretty sure Feliks misscrambled (usually after a D-- there will only be U'); if you're used to scrambling megaminx accurately, you might have mentally autocorrected the D-- U to D-- U'.

    Edit: I was wrong about the misscrambling! qqtimer (the timer Feliks used) actually generates scrambles where the direction of the U move is independent of the preceding move. However, csTimer's and TNoodle's megaminx scrambles have the U in the same direction as the preceding move.

    Wow I completely missed that all three or so times I did the scramble. This is what I get for practicing mega too much. Sorry about that.

    D-- U' is the same as U2 y2', so it's still a 2/5 turn. D-- U would cancel into U' y2, which is only a 1/5 turn. 2/5 turns tend to mix up the puzzle pieces more efficiently.
    The actual reason is probably something more like "that's what Stefan Pochmann coded back in the day, and nobody bothered to change it".

    Speaking of unusual events to reconstruct, I reconstructed my square-1 pb (super-lucky 32.76 - I'm still a beginner):

    Scramble:

    (3,2)/(-3,6)/(0,-3)/(3,0)/(-3,0)/
    (3,-2)/(0,-3)/(-2,0)/(-3,-1)/(5,-4)​

    Solution:

    (0,-2)/(-2,0)/(-3,0)/(-3,0)/ cubeshape
    (1,0)/ corner orientation
    (0,6)/(3,0)/(3,0)/(-1,-1)/(-2,1)/(-3,0)/ edge orientation
    (-1,0)/(3,-3)/(0,3)/(-3,0)/(3,0)/(-3,0)/ permute yellow corners
    /(6,6)/ switch layers
    (-1,-5)/(3,-3)/(0,3)/(-3,0)/(3,0)/(-3,0)/ permute white corners
    (0,6) AUD (EP skip)​

    So I got my first sub-20 feet single, but I can't reconstruct it

    19.48 U' L' F2 D F' U' L' B U R' F2 L2 F2 L2 U L2 U' F2 D R2 D'

    I know I started with z2 u' R2 B' U2 R'
    I remember noticing the blue red pair but I don't remember how I did it
    I'm pretty sure the solve ended in L' U2 R U R' U2 L into PLL skip (possibly no AUF?)

    Could someone help me reconstruct? I would really appreciate it

    Just got a 3x3 pb single and am struggling to reconstruct.

    Generated By csTimer on 2018-7-8
    single: 6.779

    Time List:
    1. 6.779 F2 U B' R B' U B D2 F' R' D2 L2 U' F2 U F2 U2 L2 U L2 D

    Pretty sure i started off with z2 U R' F R D F' but I'm not positive. I assume I took the three move pair from there but idk. I know I ended with sexy sledge into either U or U' auf. Any help on this would be great
