Not bad at all for a +6, yay! So why is he so high by +10.5 already in the AM? Hmmm. Could be b/c the PM shot is late it just doesn't have enough duration once any overlap is lost. Or it could be the whole mystery AM high # thing he has.
There's still room for a lower nadir though at night, so maybe rather than trying to solve the mystery, just treat the number, and I think he can go lower both day and night cycles, though the night one is really quite a bit better than the day one.
I'm feeling stumped at the moment, LOL, I will try to study the SS maybe tomorrow night when I have more time and see if anything clicks.
If it ever works for you to get nighttime spot tests between the +6 and the +10 to try to figure out at what point he is going higher, that would be valuable data I think, hopefully. Of course it is valuable sleep time

and as a non-morning person, I don't know if I could do it frankly, lol.
