So I just got my first Red run done, it was 2:16:05, and I'm wondering when the best time or times to use instant text is. Normally I just activate it before Misty and keep it until SS Anne rival, but is there a better time to use it?

Thanks!

IT is allowed again. First time you get it is after you take the pokecenter in cerulean city, then you pick up the rare candy and fight nugget bridge with IT. The next time you get it is before misty.
