RE: Throttle, I personally find applying less than 10% throttle while brake helps keep the car rotating through the turns and helps even out the wear without increasing it, using no throttle at all through corners = time lost + making the fronts do too much work in FWD cars. Look at the telemetry from top racing drivers, the best ones do this, even the ones who drive in a series where they need to harvest/regen hybrid or electric power, as soon as they're off the brakes they're on the throttle at the soonest possible opportunity.
RE: "Brake less hard", I think what you mean is don't use the brake as an on/off switch. Also, I've found in GT Sport that the brakes perform better when you never apply them past 80-90%.
Lastly, if you expect to be able to brazenly stomp and stab the throttle + brakes as if it's a PS1 game then I've got a reality check for you; the best drivers in the real world are usually the ones who can push their car whilst looking after them. It's why Schumacher had less breakdowns than all of his team mates, it's why Jim Clark was able to get the fragile Lotuses to survive F1 races, and it's why Tom Kristensen has 9 wins at Lemans + 6 wins at Sebring.
If you think racing isn't enjoyable just because you're having to try do the same things that all race drivers have to do in the real world (even those who race in short races) and want to use the throttle + brake as an on/off switch like a PS1 game, then I suggest you go do something else with your time. You will never improve with this attitude.
