You won't get enough speed if you touch any wall + you need the cable car to be pink at some precise spots.
My tip is to follow the shadow ^^
I just closed the game so I cannot show you screenshots, but this may be sufficient for you to get an idea of what I mean
To know when to let go the cable car and when to re-grab it, use the wooden thing on the floor as markers
You need all of these to get it I think
I can't use OBS cause my laptop now is slower,but thanks anyway!
how to prevent spawning romans on the left
You all are regrabing cable car
but if you just grab it and don't let it go while going backwards then they are most of the time not spawning or just spawn on the right instead on the left
most of the time when i have grabbed cable cart and going back to get momentum they are spawning at that moment

I think I didn't say that here
But I got both TAS cycle and stone skip in my last attempt yesterday
I re-grabbed the cable car and the romans just didn't spawn
However, I had to re-grab it later than usual because the gladiator was chasing me
