Yup, it is certainely draft or taking a shortcut (drive on the grass for exemple, which can sometimes help you to make a better time, but then the replay couldn't be sent on lfsworld)
Mmmhm, on top of that, drafting comes into play, as said elsewhere, which obviously can't happen during hotlapping, and the wind is also a pretty large factor, as again you can't have any wind in hotlap mode.
you can but it is very risky.. you gain very little time.. trust me , i was a demo till last year and i tried lots of times with the FBM and didnt work coz it had slicks
But I've also heard rumors of drivers, very fast drivers, that don't upload Hot Laps because it will reveal their spring rates and some other expose able setup configurations when they do. Makes a lot of sense to me if they have put a lot of work into these settings.
But still a large portion of it is the combos they are limited to.
I'm not sure which cut you mean, but to go around chicane from left is never as fast as going trough with FBM. Even if you are very very lucky to not hit wall/tires/blocks, you are entering the long straight from grass losing lot of acceleration speed. I think if you would be very very lucky with the cut, you can get just about 0.2-0.5s penalty at straight end (vs aggressive-but-clean chicane driving).
I have seen different thing at demo servers... ending the lap in pit-lane with ignoring 80km/h speed limit, that's definitely faster.
Anyway, 12 low is well possible with drafting, if others are cooperating. By ordinary overtake you would need to be lucky to gain time, usually you gain some speed, but the overtake itself includes serious time penalty to make this advantage void. Only in rare occasions the overtake maneuver happens in the "sweet" spot when you get very little time penalty, but lot of speed boost, so in the end you profit. But some people simply CAN do lap under 12.5. (not me, I'm stuck around 12.9 and happy with any 12)
haha want to see 23:4x or 5x by that LOL
BTW if someone say 1:11 is easy he never raced fbm or he is bawbag ... I know just one super person who is now playing bl gp (trismo,trema,tasuma) he made 1:12:2 with draft and he is the best on the scene now... Maybe he would make under 1:12 but with lucks and chance of make that is 0.0xxxxx% I think real good driver give the setup to everyone maybe just oval not. Nobody would be better than he with setup because setup is a part of work... Trismo gave setup to everyone and i dont see anyone faster
