It does look like a bounce or that Zeke was munching on contraband.
With TR, you may have been holding Zeke's dose for a bit long. Zeke's been at 1.75u since 11/13. With TR, you evaluate the dose every 3 days/6 cycles and increase if the the majority of the nadirs are outside of a normal BG range. I'd increase his dose unless something happens between now and PMPS that indicates otherwise.
In addition, please get a "before bed" test every night. (I'm not sure if I'm recalling this correctly but do you work PMs? If so, ignore that comment. However, if you do work PMs, you might want to indicated that in your signature so we don't keep asking you to test when you're at work.)
