A bit of housekeeping....
Remember to add the PM +11.5 to your spreadsheet. It's very helpful to see that quick rise in numbers between the +11.5 and AMPS. It will be useful when you see another lower pre-shot!
Typically, we don't suggest using a fat or skinny dose until your cat is closer to what is an "ideal" dose. Shooter is flirting with better numbers but isn't quite close enough to being regulated. I'd encourage you to stick with 0.25u increases and decreases unless there's some compelling reason not to.
And yes -- shooting low numbers is stressful at first! I often encourage members to give some thought to what number they are comfortable shooting. Once you shoot a lower number and start to build your confidence, you can progressively lower the number your able to shoot. Stalling for a bit is also a way to see if numbers are on the rise.
