Nothing. You are still learning what works for Nico and Nico is still adjusting to new numbers.
I've read conflicting information from senior members about this. I like your analogy, makes sense to me. Thanks for sharing your thoughts on this. (Another one to bookmark!)
General observation, one thing that does seem to hold true is that dry food/treats stick around longer in the system, keeping numbers higher longer than than wet food and the effect may linger through to the following cycle(s).
ECID, every cat is different - this is where you need to find out what works best for Nico. Even though Nico grazes does he seem to eat more LC at certain times during the day? Does it seem you're putting more food out at around the same time every day? Maybe keep an eye on it, note his eating pattern, see if coincides with a rise in the BG or appears to slow downward momentum. When they graze sometimes it's difficult to see the true impact LC has on the BG.

Scroll to Post #15 by Marje and Gracie talks about "feeding the curve" and how to prevent kitty from dropping too fast and/or too low.
It's a long read and not all information in this post applies to you and Nico, but it's a good read with good information and may give you some ideas where to start.
Halfway down this post Marje has a section "There are important things to consider when you are determining whether to feed lc, mc, hc:"
Please note, for anyone reading, hypo numbers need to be handled different than discussed in the above thread. The
How to treat HYPOS guideline for feeding and testing should always be followed when treating for low blood sugar.
