That third elevator video only tells half the story though. Yes you go on that spring (start running for the ladder just as it hits the ground the second time) but you have to train yourself to watch the next spring as well as you start up the ladder. Because if it's another long spring you will still die. This what Steve Wiebe meant when he says in King Of Kong "... you have to know when to retreat".
If it's another long spring you gotta retreat asap down the ladder and back to safe spot from where you ran from, and then go through the procedure again. It took me ages to master this. It's so easy to just "go for it" as you are climbing the ladder. But about 25% of the time you still won't make it.
Oh and yeah.... that arcade looks awesome.

All those machines look like they are fully restored or something.
