alot of the trouble- besides breaking points- lots of time to be found there and applying to threashold- before lockup, is turn in.
placing the car at apex does not mean you arrived there the same way.
turn in point (as you stated cyba sheep) is when you start going towards the apex.
as the driver you watched salmmed on the brakess and started turning slightly that's part of it. when he started the turn to aim the car just right.
now set ups do have alot to do with driving style, but in a world like LFS where everything would be the exact same, the driving style should be pretty near the same to go as fast in the same place. this is not to say there is more than one way to skin a cat.
I had a race at westhill, in the FO8 and we all race 1:26.xx with my speed being just the average and cathcing up in places other would slow down too much, and some place i would be left in the dust only to catch up later. We all were within .5 secs of each other till the end. 4 cars and very dicey- quite scary doing it.
different set ups different styles same times-
so copying some one when you are not that type of driver might not work for you. after years of driving (since s1) i am still no WR setter, but i never come in last anymore (i don't drive every night either- N2K3 needs love, and F1C and GTL, and CounterStrike and Day of Defeat, and Spirit of heat..)
