What is the largest jump in LEGO instructions? What is the largest gap in LEGO instructions in terms of build time needed to complete a step? For example, Skyline (5526) includes this step:



That is quite a leap between steps 14 and 15. I'm curious to know if any sets leave more up to the builder than this.

I saw this over on Reddit and thought it might be interesting to get answers over here.
Car Chassis 8860 gets my vote for complexity of a single step.  



The instructions are laid out so that you have two pages like this on top of each other.  I was building this model with my 11 year old son recently, and at almost every step on the last couple of pages we found we had missed something from the previous step.
