Nice little surf.

A common suggestion is to give a couple tsp LC (if they'll eat it

) when they first see green, to try to encourage the surf, or hanging out in those nice numbers. You might want to keep notes in the Remarks section of what extra food you gave and when, to see what works/does not work, and what to do next time you have a similar situation.
A couple other observations. Sometimes a flat yellow cycle precedes a cycle of action. Looks like you might have had flat yellow last night. Second, later nadirs tend to happen in bounce breaking cycles. From a quick look, it seems Charlotte's later nadirs happened when she started the cycle in pink or worse. Cycle five was often the action cycle for Neko too. Keep track of how many cycles after an increase you typically see action and it might help you plan future increases, should you need them. Of course, cats don't read the rule books and have the rights to mix it up.
