I remember back in the days of gt4 I used to run against my own ghost in licenses and trying to make a new record on nordschleife whit different cars. I mean after I completed most of the career mode and even some of those insane endurance races. So for me the TT's are basically the best thing ever happened!! I mean I used to do this "pointless" hot lapping just to see if I was up to it, now I even get to compare my self to others, finding out that my routine of finding limits of the track and the car has made me a pretty decent driver
So my point of view is that there is absolutely no better way to improve your driving than doing as much hot lapping as you can!! And believe me, there's no better feeling than suddenly realising you have improved your lap whit second or so from your previous best even though you though you just made the lap of your life on previous record.
A great tip is to check out those top 10 playbacks, I usually do the best I can, check out what the 1st is doing different and try to copy that or think how he does that, there's usually a lot to find there.
Oh jeah, beating your time over and over again is gonna make you more confident. You just have to start from the bottom and it's probably gonna feel devastating to see you are nowhere near the top even what you do but you gonna get better 👍
this guy beating hes head on the wall is quite relevant to my post
