78Pontiac, there are different ways of looking at it, IMO. First would be that a vehicle that doesn't have to undergo cold starts for the number of miles accumulated -- traveling salesman versus retired grandmother -- is less likely to have cold start engine wear.
Second, to conduct a test that covers far too many variables of starting keeps even general rules a little vague. I recently had a look at a 1973 Chrysler Master Service Technician Bulletin on starting. The "rule' was that the longer it sat, the harder it would be to start -- lean fuel mixture, mainly -- and that waiting 15-20 seconds for the engine operation to stabilize was adequate before kicking off the fast idle prior to putting the car in gear. Yet these "rules" don't apply so easily in cars with modern batteries, EFI, better construction, etc.
Third, I think the list you have is more than comprehensive. The hard part in my experience is in keeping to it winter & summer, for all situations. Many of don't drive a morning commute anymore -- could be going off in a hundred different directions -- and establishing a "wear pattern" is one of the keys to good maintenance.
I believe that, on an used car, it takes a new owner about 10,000 miles to re-set the mechanical relationships to his pattern. For good or bad.
Consistency is the name of the game. And keeping careful records -- especially trying to note patterns over 30-40,000 mile intervals -- to keep maintenance expenses at an optimum level is the bigger picture here.

DRIVE IT FOREVER: "Your guide to long automobile life"; by Robert Sikorsky.
He does a fine job, at length, in covering this subject.
On my 32-year old Chrysler, I leave the house, drive 5-miles thru city streets, hit the freeway and cover 25-30 miles prior to running errands, what-have-you, if it hasn't been driven in a while. It's a "warm" motor the rest of the day.
At least once a month it goes for a 100-mile easy drive. That has worked for me on a number of cars which have gone 150-250,000 miles in daily service.
