Well, back on the discussion of Schumacher's driving style. Tbh, I think the main difference between Schumacher and other drivers is bravery. For example, when braking for T1 at Blackwood in the XRT. If you brake at the 125 marker, you'll go through the corner comfortably and you can get the car to the apex without any real difficulty. Now, I've personally tested it myself, you can actually brake at 110-100 meters which is better but obviously, it'll require a bit of work to get the car into the corner but it is faster. The difference between braking at 125 and 110 is calmness. When you brake at the 125 marker, you can brake hard, then let go of the brakes where you're in a period of not having any brakes or throttle or just "coasting" to the apex then when the time is right, hit the throttle while braking at the 110 mark, you have to brake all the way till the apex and then you instantly switch to putting the throttle in.
Like what Herbert was saying, drivers like Hakkinen and Senna keep dabbing the throttle as they approach the apex and also use it a bit for the exit. I think they do this to keep the car balanced and not having too much weight at the back or front when it comes to weight transfer. As for Schumacher, he probably sets the car up so that he can brake hard and late into the apex with the car still being stable then instantly applying a small amount of throttle after he's finished braking to keep the weight at the back thus giving him rear end grip then he can just gently power it out not to lose traction.
It seems quite simple but like I said, I think its to do with bravery. Actually, something which validates this point is what Watson was saying about how fast Schumacher went through Becketts.
