Light-shield and Power-shield

[big sleep]

sorry if this is a noob topic, but i can't find a clear answer to this question.

i light-shield with L. i turn light-shield off for R so that i can power-shield better. let's say a friend of mine has the same controller set-up. if i pressed L and he pressed R simultaneously (let's assume that the spring is out of the R button and that we actually do the inputs at the same time) which block would come out sooner? from what i'm reading on smash wiki, our shields would come out on the same frame right, mine being light-shield his being power-shield? which frame is that, frame 1?

can someone walk me through the frames on shielding or at least share a useful resource i'm not finding? i'd like some clarification on this with specific frame data.

I wrote that part. It’s accurate.

thanks for everything you do for the community. your data is gdlk.

"By pressing L or R during an actionable grounded frame, the Guard animation will be triggered."

what is the start-up for GuardReflect (w/ digital input) and GuardOn (w/ analog input) AFTER L or R is pressed? in other words, how many frames does it take AFTER the input is received for both types of Guard to become active? is it frame 1, frame 2, orrr?
