In principle I agree with you. Unless you max out the potential of a setup, it's pointless to compare as you get better.
I am going to compare the cup 1 with the cup 2 tyre in a track that I have over 1400 laps with car (~1000 with the CSL) and 150 with bike.
The only option for me to go faster in this track is if I cut through the grass and skip parts of the track
This is how fast I drive the CSL there.
I have the consistency too; I can drive lap after lap within 200ms.
Going in this track with the cup 2s is what I am going to do and I will compare the corner speeds between the 2 tyres.
I hope this makes sense.

However, might I suggest that instead of cup 1 vs cup 2 comparison, if possible we do a cup 2 vs any other modern R tyre (e.g. AD08R, R888R, TrofeoR). That way its between choices we would actually be making.
My guesstimate is that the cup 2 will be quicker on the clock than people are giving it credit for. Granted that consistency/staying on point could be an issue on the relatively heavy M3/CSL as reported by others here. Plus its about all round wet/dry use where the older cup 1 (for example) was not as good with standing water.
Ultimately it does also depend on style/objective of the driver's track outing. I do interrogate my video logger after track events and hence do keep a sharp eye on my driving performance (notwithstanding I'm not a pro)/the car's performance/the tyres at every event. The real world indicator being the lap time.
Hence for me the pace over a decent 30 min stint (in the afternoon when temps/pressures have all settled down) is key.
For others who may not be into the data side of things but enjoy dicing with friends/just driving as fast as possible, they may rate a tyre differently based on things like operating window/longer stint performance etc without perhaps an eye on the lap time.
Anyway, looking forward to what Alex may find against the clock.
In the meantime, I may be choosing between AD08R and Cup 2 for my CSL rims. Both have performed remarkably well on other platforms for me (AD08R/XBow and Cup 2/911s) but I've not tried on the M3. On the M3 I've only tried the R888R which were great on track but too noisy/rumbly for the road. Welcome any thoughts.
