MaccaX custom coaching

Hi just wondered whether anyone has used (or knew someone who has) the MaccaX custom coaching.

I like the idea of a plan incorporating the MX12 sessions but wondered about the levels of feedback and input, whether they use HR/power files to adjust plans etc.

Thanks

Wondering the same thing.

Also, how custom is it. I work 4 days on 2 off. Some custom are not that custom.
