T4 at summit may be that way for you, or entering the uphill esses.
I don't lift to slow down, that's the difference. The only time I lift is if I f'ed up the turn in/corner entry and I need to rotate the car, the rotation (what I was talking about) comes from weight transfer. If you are lifting you are not going as fast as you could be. If you are not using 100% traction then you are not going as fast as you could be, lifting does not use 100% of traction, only turning, acceleration or braking does.

Read the skip barber book, it devotes a few pages just to the analysis that braking at a lower adhesion level for longer (or in this case, lifting) will result in much faster lap times than braking at adhesion limit for a shorter amount of time but overslowing the car (even by a little)
Sorry, I just don't buy it. Why would I lift off the throttle and enter a turn? If you are doing that and getting around, then you can enter the corner hotter and use your brakes to slow you down later and not just lift like a pansey. Why not just stay on the throttle another second, 1/2 second, whater, and then use brakes that can slow you down MUCH quicker than a lift? It just doesn't make sense. Even if you have to trail brake into the turn if will be faster.
