Probably. But go up slowly. If you can measure 1.2U, try that, instead of hitting 1.25U just yet.
Also, I hope we can help you when you have to do shots earlier than +12. You really need to lower dose some when you have to shoot early. Shooting early is the same as a dose increase, so by lowering the dose a bit (about 12-15%) you prevent the dose from dropping BG too low.
Buddy may just need slow dose increases until his system gets more comfortable with lower numbers. It's like he's constantly fighting those good numbers. His liver is confused!
