If you have a healer in formation you can pretty much run the hard lab without worrying much at all about needing to hit a heal-pot event so that opens up a lot of movement flexibility.
That, and when you get a +4 gain move destiny event try to find a repeat 3rd event square to double or treble it and then avoid the destiny events after you are +4 - +8 free moves ahead. Also you can change event on last event prior to end to get a double-bonus or take it a square or two early and skip past other events to get a 2x completion bonus where it counts +50 x 2
