Between 3 and 5 like that worked. I ran out of gas but still got gold. I was at that for about an hour. Clean lines is absolutely key, a bit of improvising off of the driving line getting it even tighter and really pushing the limits is what you have to do.
Nah, youll get it. Its a pain for sure, but this method was fine for me. I already had gold, just didnt want to remake the video. (I dont voice over it later, i talk as im actually driving )
