You don't say !
I wish I could know the ring better but I am not playing 4h per day, I am happy when I can play 4 hours per week. And there are plenty of other things to do in the game than C.E the ring. (For example try to get some credits to buy cars you would like to have, or just have fun doing something else than ring-ring-ring-ring)
Gave it another go tonight, failed the lap 3 times at various points (thus I practice much less the end of the track), and managed a full lap at fourth try, beat my 7min07 with a 6min55, still a long way to go.
Have absolutely no idea what I am doing in many corners, if I try to pass them like I do in each individual sector (trying to mimic the demo), I end up killing myself everytime, so I go more cautiously to avoid crashing, and I have a slower time in the end, obviously.
There are too much corners and I can't memorize so much breaking points (I am using AT, so I don't have to memorize the speeds at least).
That track may be easy, if you have a very big chunk of time to learn it and are able to lap it for hours. To much focus for my energy levels. 1 full lap is plenty enough each time I try.
