You are stupidly jacked. You also grew an inch in a year: that’s awesome!
Honestly, with the results you have, you have a handle on things. Why not just keep doing what’s been working?
For myself: nutrition supports training, not the other way around. So I wouldn’t need to jump into high calories straight away because I wouldn’t have that much demand.
I’d include low-carb 6 days a week, and just have 1 carb meal per week
