I know they will be slightly slower

Citation needed. The rolling resistance is very close, and the tread on the GP4000S seems to act as a trip, so some wheels have less drag with a 4000 than they do with a completely slick tyre.

You keep saying this, do you have a source?

Not off the top of my head, and I'm not about to embark on a lengthy quest on my phone, but that new Swiss wheel company (Swissside?) or maybe Flo tested different tyres and one or both found the 4000s had good aeros IIRC.
