"Feeding the curve", is feeding earlier in the cycle and not feeding much food past mid-cycle (+6) to keep the numbers a bit higher at nadir and prevent those really big drops which lead to really big bounces. The idea is to get a more broad, gentle U shape to the curve, more like a smile than a sharp V shape.
Try to picture the numbers for the cycle on a graph. My mind can see that curve shape when I look at the numbers on the SS.
Feeding the Curve (dives)
When a cat drops hard and fast, it helps to try and flatten the curve so they don't drop down too fast and then swing back up high in the second half of the cycle, > +6, because they took such a steep dive. Go take a look at Kit's SS and you will see that Kit is being fed on a front loaded schedule. This is to flatten the curve.
If a cat doesn't dive and has fairly flat cycles, they can be free fed and don't need a plan to manage the curve. But if they dive, you might want to think about dividing the number of calories/day into the two cycles and then feed mini meals on a schedule.
Most people will feed their cats the largest portion at PS, and mini-meals later. Such as at +1, +2, and +3 to control the dive. It doesn't flatten the cycle over night but patience and it does help. You will also have to see what helps your cat best. Maybe it's PS, +2, +3....and if you work, you may need to use an auto feeder.
Kit is a "champion diver", so J and J are trying to slow those steep dives and the subsequent steep rises by feeding food at different times. It's why there are such extensive notes on the SS in the remarks column. To see what impact the food is having on the cycle.
Sometimes, the drop is a bit more than desired, and Kit needs a bit more food to bring the BG levels up like on 3/27 and 3/28 AM cycles.
