Holas! Sorry I can't speak Spanish too well but hopefully I can offer some explanation.
edit: My first post asked if KERS was allowed before as I didn't know it was allowed now and after some testing, I see it is allowed. Since KERS is allowed, the cars can go faster with quite a big difference in times than without KERS plus after a few laps, the level of KERS restores itself a few times so it would make everyone's cars and laptimes faster, but also, equally.
It would make it equal because we all have the same amount of KERS. The only difference I think is when it is used and how much time a driver can effectively use it. Say for example, you're on lap 3, you are about to start lap 4. If you use KERS just before lap 4 and cross the finish line, KERS will restore itself to full so you got an extra boost and a full level of KERS now how you use that remaining KERS is up to you but the amount of KERS available cannot change as it's the same for us all.
The record holder's times are valid, I've followed many very closely to see how they take the corners, when they turn, when they brake, when they accelerate, and noticed there isn't a big difference in times that are close to those which are also nearly the same when they go around the track.
I don't think the records would be reset though since the cars are faster. It's only when in the past, a new version of MRO was released where the physics included the car spinning and tire wear, that the records had to be reset because in many tracks the times were not possible due to physics. As the physics changed and the cars became more realistic, that's when MRO had to reset the times.
Hopefully that helps explain it! Cheers!
