Yes, if that +6.5 is up again, it's ok to leave him some LC food, and go to bed I think. Poe never had any terribly low numbers so it looks to me like he will be safe for the rest of the night.
It would be a different situation, if Poe had dropped to the 40's or 50's and been fed gravy foods and/or syrup. They wear off and you want at least 2 non-food influenced numbers over 100 before you can safely go to bed.
I think we got a nice surf for Poe this evening.
