what I'm noticing on Gus' spreadsheet is more flatness (anti-jinx). I think that is a good thing. Sure, flat is nicer when it is in lower numbers, but once you get them flattened out then sometimes it is easier to just keep tweaking the dose until the whole range starts to shift downward. Of course sometimes it is not that easy!
I really like what you have been doing with Gus. Even when he does zoom up, you have been able to get him down fairly quickly and usually without setting off an even bigger bounce.
If his mouth is still healing, that can definitely affect the numbers. Hopefully it will keep getting better.
