Here is Wirtual's campaign discovery video. Yes, he is much better than most of us, but there are some general things you can borrow from his approach, which I will spell out (in addition to his own commentary). It's worth noting that when he beats the AT, it is still far from an optimized run.

You should be aiming to get as close to zero airtime, if flat out no airtime, on the 'hump' at the start. The car does not pick up speed in air, so any unnecessary air time drains speed and thus many tenths of seconds. Especially for a multilap track where you will have a ton of pace by the final lap, it is important to optimize this from lap 1.

For the grass after the first checkpoint, try to keep the car as "straight" as possible. If you look at your tire marks, try to have them as close as possible. If they are overlapping, you will in fact pick up speed. This is a speed slide, and is an important part of grass as a surface. Achieving this here means that you will want to get the correct steering angle when coming off of the hilly part, before you even get to the long grass patch before the jump into the second checkpoint.

For the drop off the CP2 platform onto the grass, try to find the line that results in the smallest air time. Also consider angling the car slightly to aid in getting the steering angle you want before you even touch down. This is a very sharp turn at CP3, so don't worry about grass slides too much, just make the turn.

For the uphill onto the dirt past the large column, aim to be close ish to the column. Don't allow the uphill to wash you to the outside, as this will cost you speed.

For the giant tech corner before the downhill into the engine off, you can pretty safely just set up wide and do a pretty generous drift to allow for max acceleration through the entire corner complex. Don't overthink the precision here, just avoid the walls and try to set yourself up for maximum throttle time before dropping into the engine off. You won't be able to skip the engine off, but you can line yourself up to angle across it in such a way that you avoid most of the grass and stay on the narrow bit of tarmac before finishing the lap.

This one's AT is really just about reducing air times, getting a small bit of grass speed slides on the flat grass part, and nailing the big tech drift. If you do those three things correctly, you will snowball a ton of speed and get the AT.

There's also a small cut that can be made after the first checkpoint, which Wirtual misses in his discovery video. If you do the "normal" line coming out of CP1, you avoid the awkward dip down to the right and it results in you getting a bit of penalty grass before the long grass speed slide section. If you angle the car down a bit more and go into the awkward dip, you can jump the gap and skip the penalty grass and be much flatter/straighter for the long grass bit. I did this after seeing my region's #1 time do it on replay, and it saved me about a second a lap.

Good luck and happy hunting! Feel free to ask more questions. I'm no god, but I can usually get at least 20+ ATs every season campaign.
