Very good information here, and after studying the post at the link that timhett posted (back when I realized that elevators was a major weakness in my gameplay), I determined that facing the ladder with jumpman facing the ladder and the front of his foot at the line shown in the below picture is about the closest you can safely get to the ladder, in order to get a good jump at the ladder. This is an aggressive position, though, so timing your "leave time" gets a little bit tighter than if you were a couple pixels back like shown above.
I've found, and noticed the greats doing it before I really started doing it comfortably (it just started happening naturally for me, wasn't anything I really tried to develop as a skill), that the more comfortable I get with the spring timing and jumpman's positioning left of the ladder, I am able to watch the spring bouncing at Kong, and then cheat towards the ladder while watching for the second spring, and kind of "wiggle" back and forth at the waiting spot to the left of the ladder.
I detail this in my blog, but the elevators was definitely the sticking point for me until I started studying how to get better and focusing on practicing practicing practicing. My PB was 178,000 until getting proficient at springs.
All that is to say good luck sir, and keep going!
