Starting another Valium taper

Hi again all! After reinstating on clonazepam for quite a while, I'm ready to start a new taper with Valium.

My question is this: if I were taking clonazepam more than twice a day, do I need to also take the Valium at the same times of day?

I know Valium lasts longer, and my last taper I took the "V" at the same time (2x/day) as the "K" - or does it even matter?
