A very rusty delivery of the routing, featuring a bounce off the surface of Minmus resulting in 6 broken solar panels, one lost engine, and the potential to take this category sub-40.
Huge time-save coming from an update to routing that has me loading Data into the Mobile Processing Lab, LIVE -- during warp. Keeping the lab humming at maximum efficiency throughout.
Especially those EVA's, at a value of 44 data, keep the rate of science production at its absolute highest, which allowed the fastest generation cycle in this run to produce 500 Science in just 9 seconds.
Considering how much time loss there clearly was in the delivery of this run, I think those last 4 minutes to sub-40 are just a matter of grind, and knowing precisely where each bit of your Science is coming from.
