If the engine were generating at 7000 rpm while breaking, and say it would be at 3000 rpm when the driver re-applies the accelerator, then after the driver pressed the accelerator, the engine would have to stop generating, decelerate down to the required rpm and then be reconnected to the drive train, in the process generating a massive amount of throttle lag. furthermore, such generating would easily be audible in the video reviews, and surely the reviewers would have commented on the engine constantly spinning despite being on the break.
I agree with your point, its impossible for the P1 to use the engine to generate power when off throttle as the drivetrain would be the one doing it, spinning the motor. if the engine was the one recuperating energy, both the engine and electric motor would have to be disengaged from the box meaning zero kinetic recovery. So if the P1 uses regenerative coasting and not braking, it will not harness enough energy for a full blow lap. I think this is why McLaren has a electric boost button there, like on F1 cars. When there is enough charge then push the button but while it is not being pressed, what is left in the battery is used for touque fill to cover turbo lag.
