Hi, just made a new track recently and thought it was ready for posting...
Notes:
The ideal speed to leave the ramp at is between 50 and 60 MPH.
You need to start decelerating well before you even hit the ramp.
The ideal time to start turning is just before you leave the ramp.
This track is not reversible without some serious physics abuse due to the trajectory the car leaves the ramp at.
The car will always pass by the track, slightly to the north of it, rather than landing on it, if done in reverse.
This could possibly be fixed, but it wouldn't really mean anything, since the only difference
between a forward and a reverse run would be the direction you turned at the edge of the ramp.
Attached below is a replay file of my fastest run. It took me a few hours to find the "sweet spot" so I could get repeated successful runs.
