Trying to figure out how you did it DrTChops but I can't find a consistent way to do it.

I think he used a mouse with a freescroll :)

Not sure if you are right, cause I tried this with a jump spam macro I made and couldn't even get the same jump consistency. Although I could make it almost halfway before every landing caused damage.

I found out that unless Dr was going slower than he wanted to jumping and blinking on those rails, it is actually faster to go on the roof above the cart, blink onto the vent/pipe attached to the far right corner of the building, blink/run on the path left of the tracks, blink across the land bases under the tracks and up to the mansion, and you can save 5-10 seconds not going on the tracks. Only timed it with how fast I could do it while Dr's WR was playing along side.
