As i already said, Rubens was using his right foot for both braking and throttle, that comparison shows that difference, if you take away the time he loses when switching from throttle to brakes, the times would be very close. It still doesn't change the fact that almost none of that article applies to the car we're talking about, it definitely doesn't mean you should be on the throttle while in a major braking zone in the Stratos, you're comparing apples and oranges here. That article also shows qualifying lap data, i highly doubt Schumacher would be doing this throughout an entire race, the car just wouldn't be able to last.
Dabbing the brakes here and there to change the balance of the car is something i said was useful, but what you originally said was to never lift off the throttle in a braking zone, that's what i'm telling you is wrong and quite frankly makes little sense to me.
The highlighted text doesn't make sense to me, how would you manage to get the car into gear if you're sitting there with the throttle open the whole time? That may be useful in an F1 car with traction control and fuel cut-off during shifting if you're going for a hotlap, but the disadvantages outweigh the advantages after a few laps even in that rare situation. It's not something that you would even be able to do for more than a few laps at most in a road car with a fully manual gearbox, you would wear down the brakes, the gearbox, and the clutch to nothing. So again, you can't compare an F1 car to the Stratos, they have to be driven in different ways because of the massive difference in the fundamental characteristics between them.
All of this said, i have no trouble driving this car and i'm not even left foot braking at all. If you're taking full advantage of the braking force of the car and getting the braking points correct then you wouldn't have excessive oversteer into a corner and therefore would never need to balance the car using the brakes.
