There could well have been a bit of 'unlearning' a few years of his blown floor technique but I personally don't think it's that simple.
Webber had, in the past, mentioned Vettel not being that happy with a car with a loose rear end.
In reference to the early braking and early throttle I would need to know context. For example, on a tyre limited circuit/strategy like Malaysia you would look to be as gentle on the tyres as possible but try and maintain good pace. A gentle approach through the braking zone, getting the car settled and then getting on the power in a controlled fashion would be a smart approach any day of the week but would be crucial in extending tyre life.
It sounds obvious but something that is always worth noting with regards to braking distances is that if two cars have different top speeds and the same braking performance, the faster car will have to brake earlier to slow down. A common cause of the lockup or overshooting a corner is actually a driver getting a better run out of the previous corner and not adapting to the now required earlier braking point.
