P2S multi AMS drying

I’m not sure if I should post this here or in a different sub but I have a P2S with a AMS 2 Pro and AMS-HT, I set both to dry for the same duration within a minute of each other. The HT finishes with 1.5 hrs(ish) left on the 2 Pro. The only difference is the HT has a power adapter where the 2 Pro is powered from the P2S.

Has anyone noticed this or had happen to them?
