Ive recently been working on not pressing L R all the way down when L canceling so It wont effect my ability to tech if I get hit shortly after. This got me thinking.
First, how long is the period of time that you cannot tech after pressing all the way down on L R?
Does pressing all the way down to shield effect your ability to tech after?
Does wave dashing effect your ability to tech after?
After you full-press L or R, there is a 20-frame tech window. After this window, there are 20 more frames before you can tech again. Full-pressing L or R during the 20 frames after the tech window will prevent you from teching for another 40 frames.
Yes, hard shielding and airdodging (which includes WDing) all count as tech inputs. ANY full press on a trigger is considered a tech attempt.
hard-press wavedashes may actually help you...
the downward direction means easier crouch cancel and the hard-press means you get the tech if someone hits you during your wavedash
There is no point stipulating a "hard-press wavedash" because you cannot airdodge (and consequently WD) without fully pressing the trigger. However, it should be said that you are not actually CCing when you WD because you are in airdodge landing lag (10 frames), not a crouch. If you tech after WDing, it was simply because you were ASDIing into the ground (the same way a Sheik may try to ground tech an attack after landing on stage with her up-B).
I don't think that the fully pressing L/R to L-canceling thing is really a big deal when it comes to tech timings. If you time your L-Cancels as late as possible you shouldn't miss techs when you get hit out of your move as you L-cancel because both the window to tech and the window to L-cancel are large enough that most of the time they'll overlap.
It can definitely be a big deal. It can be helpful to full press your L-cancels if you think they will do something like a Fox shine OoS to knock you down, but if they do a move that doesn't knock you into the ground immediately (most common occurrence is with throws), then you can very well be looking at an impossible to tech situation because you pressed it. If that same Fox you expected to shine OoS grabs and dthrows you instead, you probably won't have time to tech because there are less than 40 frames between your L-cancel attempt and your character hitting the ground. You may have enough time if they pummel once or if your character is really heavy, but even with enough time, it makes the window that you can input the tech much closer. So instead of just teching as soon as you see the dthrow start up, you'd have to time it right before you hit the ground to make sure all of the 40 dead input frames are finished. Fox's dthrow is just one example. Plenty of throws and attacks cause you to land on the ground within 40 frames of L-cancel attempts, especially because of how common it is to DI them downwards as you try to FF your aerial.
