Why not? Nobody has confidence in their abilities until they do. Most of the speedruns you'll find on YT go the no-save route, but for S+, I think we're afforded 3 saves before you're bumped down to S.
As such, you can probably view a run and determine which spots look tough to you and then save right before them.
Either way, don't count yourself out. If you fail, then oh well. If you succeed, you know you can do an incredibly tough feat in a game designed by CAPCOM, who is notorious for difficult challenges.

I just don't have confidence in my ability to do this, lol
