Firstly Andy, I have to point out that you're an absolute legend and the fact we don't have these mods in F1 22 is stopping me buying the game; the underwhelming reviews and buggy gameplay being the other reason.
I've used various iterations of this mod over about 30 races, so hopefully I'm well placed to provide some feedback. Unfortunately I barely get 4 hours a week of game time so I can test, but I'm not the best for it.
Cold tyres after pit exit - I remember this adjustment and I really struggled with it. I always felt like the AI didn't have this problem and I was basically running on ice for a lap or at least the first 5 or 6 corners and losing lots of time. The latest version seems to have hit the sweet spot in you won't have full grip out of the pits, but it comes to you after a few corners.
Tyre strategy - never had an issue. Tend to find there is a split in strategy which makes the racing really interesting between 1,2 and 3 stoppers.
Tyre degradation - I tend to find the car starts to drop off very quickly after 40% deg on a tyre, and you need to get them off asap or lose over a second a lap due to understeer. It would be good if the user could counter this somehow for a little period of time i.e. 40% deg causes heat loss which causes understeer which means you need to fight harder to keep the temps up throughout the lap.
Race strategy - still infuriating how cars who are clearly safe from the drop zone in Q2 will still go out again on the soft compound and basically run their race strategy because of the way Codies have wired the gap - don't think you can do anything about this though.
All in all, I'm very happy with the mod as it stands
