It is in the sticky on dosing methods.

With SLGS you hold a dose for 7 days and then perform a 12 hour curve, as noted, testing every 2 hours. You can also do a curve testing every 3 hours over an 18 hour period. All data is good data, so even when not running a curve, it is recommended to try and get random spot checks in at different times on different cycles to fill in the blanks and get a feel for how the dose is working. The goal really is to get an idea of how your cat responds to insulin and carbs.
Part of this process is getting a feel for basic concepts:
- Onset - the length of time before insulin reaches the bloodstream & begins lowering blood glucose
- Peak/Nadir - the lowest point in the cycle
- Duration - the length of time insulin continues to lower blood glucose
