You don’t mention it, but have you done an Advanced Factory Spindown with your Core?

I recently pulled my Core out to use after letting it sit for 1.5 years. For the first ride, compared to the same Power Meter as before, it was 15w higher relatively after just doing a normal spindown. After the advanced spindown though, it was back to the same relative power as before I put it in storage. Something to try if you haven’t already.
- edit - Ah … it is mentioned up there in the Thread! At least I added the link
