I don't want to sound rude but are you sure you can do 3 one arm pullups? If you are telling the truth thats pretty impressive, considering Steven is probably stronger than anybody else on this forum in terms of one arms (and other stuff besides his weak little asian legs 
) so I'm skeptical.
lol, didn't know steven was asian.
you don't sound rude at all sat. if i had a cam i'd upload some video, but i don't. like i said though, my form on the third is so horrible, i don't really count it, and it only goes to the chin, not the chest like the first two. i've been doing pull ups, and chin ups, and rope climbs as well as heaps of other stuff since i was 4 (literally), so it's not like it's happened over-night. i have a gymnastics background, as well as having trained as a circus acrobat, so i've probably done tens of thousands of reps with body weight exercises over the years. so again, it's not like i decided, 'hey, i'm going to do one arm pulls and one arm chins', and just cracked them off on my first attempt. i first started working on them about 10 years ago, assisting with the off-arm, and doing negatives. eventually, i built up to it. i haven't actively trained them with the purpose of increasing numbers in several years, but i make a habit of at least doing 1 everyday. just to stay able to do them.
