IMO I never understood the need for any of those tables to go below 100, I've never seen a car get hot and require so much less fuel that a global correction needed to pull even 4% (with your 96% setting).
So that's one of the issues, but likely not the only one. There's also the CLT/MAT table that I wanted to mess with but never got a chance to. It's next to the air density correction one on the drop down.
Schmoozer Joe was telling me about how you can dial out hot restart funkiness with that, but I didn't test it much because my car was already hot re-starting good.

You will have MAT affected hot restarts if:
1) Your intake sensor is recording a real or imaginary (heat soaked sensor) MAT that is above ambient.
AND
2) You have a correction set that is less than 100% at that MAT value, so that fuel is pulled.
Your logs can tell you these things, you don't have to guess.
But, the sequence given by Scott and Vlad is correct. Get rid of excess MAT correction, then tune for normal conditions; then, if still needed, address hot restarts with slightly fat idle AFR, and EGO. I would also add some ASE as EGO won't kick in right away if you have Innovate O2 sensor.

If you can find out how to use CLT/MAT please let us know.
Oh, here is my rant/dissertation from another thread: Post 18
