All of my cat studies have been from a cold start. I set the Graham scanner to monitor O{2} voltages and noticed that once O{2}1 starts changing, the ICE 1,300 rpm seems to go a little free-wheeling. I've not really looked at what happens if the car is warmed up and restarted because it seems fairly brief.
Once I get the car in Stage-4, I pretty much try to preserve it. I don't leave it running as I go into a store but if I come back to the house for something, I just leave it in "P" and duck in and out.
One of the perverse things is I think it is more fuel efficient to use a drive-through instead of parking and going inside. This is completely counter to what I'd do with a non-hybrid.
