Another nice day!
I sss trying to figure out why he's going up at +1 and +2 and I also looked back on the feeding schedule I suggested to compare it to how you've been feeding.
My suggestion was:
PS-5 tsp
+1-7 tsp
+2-7 tsp
+3-7 tsp
It looks like you've been feeding him 7 tsp st PS, too. It's not an issue....I figure you were experimenting.
It also looks to me like he's got good duration but he's not getting any carryover or overlap. So he gets to the +12, he heads up, he gets a bit of a food spike, and then he onsets around +2.
If it were me, I wouldn't be concerned. I think you should just keep holding the dose for now u til he drops below 50 or spends an entire week in normal numbers mostly below 100. He's looking really good!!!
