for any% it's not a big deal, it's a few seconds. It only really matters for top runs. it's probably a much bigger deal in long categories like hundo but still probably only a few minutes over a 15+ hour run.

tldr unless you're going for wr it doesn't really matter

If you join the discord server, the routes for pretty much every category are pinned in their respective channels. The link's at the top of the page under the follow button.

maybe that should be clarified in the rules?
