There's an interview on Planetmountain with more substance, details, and clarity:

"Did Hubble suit your style?
It’s not my absolute ideal style of climbing. I’d say tiny crimps and long moves, more than pocket climbing, are my style, but Hubble did seem to suit me. Let’s just say I’ve climbed some 8c+ that have felt a lot harder. And I’ve climbed some 8c+ that have felt a lot easier.
Grades aren’t an exact science
No, and to get a better idea more climbers will have to repeat it. Six really isn’t very much. Perhaps the following will help you understand what I meant before about style. Yesterday I climbed another two 8c+ at Raven Tor, Kaabah and Evolution. I got on Keebah immediately after Hubble but didn’t get up it, so I sent it yesterday, then did Evolution in 3 attempts. If you ask me which of the three felt hardest, I’d say Kaabah. Which is funny, because it’s the one that has got the most repeats, the one that most feel is the easiest. It just goes to show how much style matters and how difficult it is to grade something."
