yea man, i remember having to learn all of this from text and not people. its tough without friends who already know these techs but its also pretty cool to hear them say "wtf, whats all this sliding? and why do you move so fast???"
as for shl, the fastest possible way to do this is to ff at the exact peak, so all you have to work in is the laser at the appropriate time. if it goes above their head, laser was too early. if the laser doesnt come out, too late. i completely agree with the captain that this is a good place to start getting used to the sh ff motion and when the peak exactly is without worrying about L/R. if he doesnt fastfall at all, you hit down to early(before the peak).
teching has a 20 frame period of time (1/3 sec) that l/r can be pushed (i think its 20 frames...) anyway, the most likely reason that its not coming out sometimes is that when you press l or r there is a 60 frame period where you cannot tech. so if you hit it too early, and then hit it again at the right time, it might not come out for that reason. if you hit l/r for something else, like a shield or l cancel, the rule still applies, but 60 frames is only a second so its not a serious problem. just try not to get anxious and mash it. as for tilt, ground tech you have 3 options: tech in standing position (down or no tilt), roll to left (left tilt) and roll to right (right tilt). wall or ledge tech you have two options: tech and fall (no tilt) or tech and walljump (up tilt)
finally, with wavedashing, you want to aim at dodging right as you leave the ground. falco has 6 frames of lag on his jump (i think), so thats 1/10 of a second difference between the hitting of jump and L/R. if you slow it in training mode, you can kinda see him squat down before he jumps. dodge in this time, and he does nothing. basically, if you jump and do nothing, you hit l/r too early. if you jump and dodge, l/r too late. tilt effects angle, so straight down tilt will wd you in a standing position. you can tilt any direction between down and completely horizontal (this will cause you to airdodge straight along the ground). in other words, tilt more down, move less distance. tilt more to the side and move more. a "perfect" wd is as close to horizontal as possible while still having a slight down tilt, netting you maximum distance.
sorry for the book. hope something helps you out.
