No, I don't think he's cleared the bounce yet. I'd expect to see at least yellow or blue numbers if he cleared the bounce. Bounces override any normal Lantus cycle. The only way to somewhat predict when a bounce may clear is to look at how long it took the last time.
I think Oren's last bounce lasted 7 cycles - tonight is cycle 6 after the yellow amps that i'm guessing was during the bounce cycle. So I'd guess (because that's all we can do) that he might clear it tonight (6 cycles) or tomorrow's day cycle (7 cycles.) If you see a lower amps, that'll tell you that might be happening.
There's no way to just say when to test. If you see anything lower than 300, I'd get another test in another hour or two. If I were you, I'd probably get a test right before I went to bed tonight, at the last possible minute, and if he's still over 300 call it a night. Then check at amps and see what he's doing then. I'm thinking you don't have any ability to get a mid-cycle test tomorrow during the day, right? If you could, that would be good but if you can't, then don't worry about it.
