Your 3W penalty is only at certain pressures and per tyre, btw. This is the TT thread and we wouldn't want any bad maths misinforming anyone's tyre choice.
Wrong again. It's 1.5w per tyre and was running them at 90+ psi.

What I would take from that test is that the tt version is faster and you should whack the pressure up. The load of 42.5 kg is a bit odd as the weight distribution front/rear would be very different. Even @hippy wouldn't quite place 42.5 kg on the front wheel. Also, anyone doing a tt at 18 mph should take up knitting instead.
I'm ancient, we used to use Wolber Piste 18mm tubs whacked up to 160 on fast courses, because someone faster than us said they were quick. We carried a spare tub under the saddle and a frame fitting pump. On a fast 25 course and a fast day we disposed of both, at worst it was 6 miles to a marshal with a car. If you puncture, your race is over anyway on a short tt.

Not wrong. You didn't specify which STR so I picked the worst option and your chart doesn't show Crr at 90 psi and if you think any of this is even close to the point of the original argument you've lost everyone.
Hmm, I wonder if Tarling was running Corsa Speeds...

Ah yeah the usual, It's a bike forum and I'm so serious, I think I know better and must prove it with some second-hand anecdote.
All racing, no, this is a TT thread and we were talking about 25s and my experience with tyres I was offering to someone racing 25s. You claim the tyres are crap because you "talked to someone in some event that they punctured in" with zero explanation of the nature of the event or puncture and I claim they are good because they're fast and I've had no issues with them in the multiple British TT events I've used them in. I'll let the recipient decide if they want to use them for their events.
