good job, didnt think you'd pull it off that quickly. i also have to corect myslef, it is 5 skills not 4, i forgot about the blocker thats why i thought it was 4.
little fun fact i actually found that strat while attempting to find a new even faster strat for m20 in the best ending tas, didnt find anything faster but i found a 5 skill solution so i at least got something out of it
