Sorry if this has been covered, I haven't come across a topic on this - but haven't looked real hard either....
Anyway, I noticed Hank completing the Spring stage like this on occasions and also noticed Corey do it when I watched him play a bit yesterday, so I thought I'd give it a go.
Basically, they're not running all the way right to the "safe" middle of the right elevator motor, which is how I've read how to do it, but rather running to just right of it, waiting for the long spring to sale over the top, before doubling back and straight up the ladder.
Is this a safe method? And how are they doing this, I'd assume they are still watching the next spring that comes out, as a 2nd long spring will result in death this way.
I made a quick vid of me doing it (not as well as they do, but it worked)
I've tried, and tried and tried, I just can not make get the timing down taking my eyes off Jumpman/Mario and watching the next spring that comes out - I'm hoping there is something in this method that is possibly easier.
