@@5QUANCR0W Not possible, once a piece was wrong on a 5x5 but I then fixed It then it was solved, so I cant really say anything, haven't disassembled since, can I have the notation for it?
There are 42 CLL algs, which means its a roughly 1 in 42 chance to get this case (i say roughly because some cases appear more often than others but i cant find out how often this specific case appears). There are 4 different possible aufs so that makes it 1/42 x 4 which is 1 in 168 solves. But then getting this same exact case 2 additional times in a row makes it 1/168^3 which comes out as 1 in 4,741,632 solves which makes your estimate of 1 in 5 million likely very accurate. Incomprehensible luck.
I had gotten a 2.73 using CStimer when I averaged 23 (1,3)/ (-3,6)/ (-5,-5)/ (0,-3)/ (3,0)/ (-1,-3)/ (-3,-3)/ (0,-1)/ (-4,0) idk how and why but somehow its not a possible scramble, my cstimer was acting glitchy that day I remember so (draw scram was glitching like crazy) its not counted as my PB the reasson the scram is not valid is cause the (-5,-5) cant be there, instead do a (6,6)
