Looks like they are measuring crank arm deflection, not shifting quality.
But nice that they updated their test :)
I have S-Works chainrings if anyone wants to try them.
Read the notes.
For what it's worth I've never had any issues with S-Works cranks and rings on my Tarmac. They were fine on the Shiv when I had them too but then Di2 will shift the shit out of anything.
