I don’t think this would be allowed because when your in the room some enemy’s might path find to you instead and ignore him, therefore making the run easier. If that wasn’t a problem you would have to prove somehow that you didn’t interact w/ any part of the environment. Also you running from the beginning to the end would slow the time significantly, so your unlikely to be on WR pace doing that
I see where your coming from with this idea, at a certain skill lvl getting S rank or lower than S rank is an inconvenience to the runner and doesn’t make the run more enjoyable or interesting, just really grindy. For example in JT if your going for S% you take extra time just for the credit terminals and junk like that just to say it’s S rank. Even with CBM at a certain skill lvl your not dying enough to not get S or even S+. But does it need to be removed, not right now, or ever it doesn’t need to happen. So i don’t know it wouldn’t change all that much other than people can’t as easily get a WR by going for a niche category and getting S.
