Lost interest at this:

When you adjust for the butyl tube used for the clinchers, it looks like this (I used 2.5w for the butyl/latex delta):

Schwalbe Pro One Tubeless 20.9
Michelin Power Competition 19.7
Zipp Tangente Speed (28) 20.0
Specialized S-Works Turbo Tubeless 22.9
Zipp Tangente Speed 20.5
Hutchinson Fusion5 Galactik Tubeless 23.4
Bontrager R4 320 21.9
Specialized S-Works Turbo Cotton 21.0
Continental Grand Prix 4000S2 22.0
Vittoria Competition Corsa (23) 22.3
Clement LCV 23.2

My comments: that's the best I've seen the Pro One Tubeless test and that's the smallest delta I've seen between the GP4000 SII and the Turbo Cotton. The delta between the GP4000 SII and the Michelin Power Competition is also notably larger than I've seen elsewhere. Finally, I'm surprised the S-Works Turbo Tubeless tested so close to the Turbo Cotton even once you adjust for a latex tube.

Edit: just realized the table didn't post.

"And don't worry about a 0.5w difference"

Don't tell me how to pick my first world problems damnit.
