Was Sidious going all out in RotJ?
Mostly asking about whether anything indicates that, once he got around to ramping up his Force Lightning enough to a point that would execute Luke after all that torture, is it plausible he was going all out by the time Vader threw him down the reactor shaft?
Not being reduced to ashes is already impressive for both parties for Sidious' Lightning being hilariously above Starkiller's Clone's amplified Lightning from FUII (about 40-50 seconds of constant stream vs the 3 or so from Sidious), but there's still room for more depending on any contextual evidence about how much Sidious was actually putting into his shocks. :hmm
Basically, does the novel/script/comics say anything here in more detail than the film?
