Because Henry's AMPS is always so much higher than his PMPS.
Joanna suggested I try this so there was a shorter time between his PM shot and AM shot to try to get his AMPS lower.
It has helped, when he was on 12/12 schedule most days he was anywhhere from mid 400's to over 500.
+4 241
ran and hid under the bed during storm so didn't get a +6
+8.5 195
He was probably lower at +6
