For the first one, if you do the sj.M to buster as soon as possible after 5S, you can lightning dash them, land and TK Sentsuizan them before they land (a little extra meter and damage, and if you’re technical enough to do the lightning loop, there’s no reason to pass up on free hits :)). That finisher won’t work if your combo before it was **really long **though (like if you’re using it as your second assist extension, or if you did it after a combo involving multiple busters). The sj.M to buster stop chainging.
For the second one, you can squeeze out more damage by replacing “sougenmu” with “jump chargeshot->lightning dash->sougenmu.” The lightning dash+sougenmu activation gives you enough time to charge another charge shot.
Likewise, if you ever want to chain multiple lightning loops together, you should try to end your first lightning loop with “TK Raikousen->jump charge shot->Raikousen->sougenmu” once your sougenmu runs out. It’s not really necessary since you can always just go straight to charge shot when your sougenmu runs out for the sake of consistency, but I’m a meter hog and anything I can stick between lightning loops (assuming they’re not already dead) is more meter for me to use later on.
