What is the CAS? It's simply the existing WDC with the seasons running mid-season to mid-season.
How is the midway point determined? For 1967-80 it just follows the same splits applied at the time. For all other seasons I split the WDC season in half, and for WDC seasons that had an odd number of races I made the middle race a CAS season finale.
Dropped scores? I tried to follow the rules in place at the time, counting a similar number of races. I won't list the exact numbers counting in each season as it doesn't affect the championships very much, but will do so for any specific season anyone might ask about. Obviously the split season does sometimes affect which races drivers had to drop points from.
Points system changes? Not much overthinking here, I just took the points as they were applied at the time. So midway through the 1959/60 season for example, the fastest lap point got replaced with a point for 6th.
This is all just bollocks though really isn't it? Yes Beri, indeed it is. It's fluff to an absurd degree. Lots happened in the real races that wouldn't have happened under the CAS championships.
What's more I have yet to double check (or even single check) my calculations, so if anything feels iffy or better still if you come up with a different outcome then let's hear about it.
With that said, here is the roll of honour (subject to corrections) of CAS world champions to date, followed by a list by driver of CAS titles and how it differs from their WDC tally. Apologies in advance to anyone called Rosberg.

The gains and losses don't cancel to zero because at the time of writing there has been one more CAS title than WDC title awarded (ie the 2023 WDC is still ongoing. In theory anyway).
