We use focus track all the time. It is often far moe efficient than ladders and lifts, and it allows us to get over box sets or raked decks easily. Our track system is a custom built system, and we are actually looking into updating it with some new track and carrier tech. As focusing by focus track typically involves flying people, I won't go into the details of actual operation. Suffice it to say, anyone operating a focus track system needs proper training to do so.
I assumed he meant Focus Track - as in the cue tracking lighting software.

Focus Track was used to calculate the entertainment lighting loads at Seattle Rep., and essentially debunked the theory that converting a large theatrical incandescent lighting system to LED would see the purchase price of the conversion paid back via savings in the electric bill.

It would be interesting if console developers could come up with curves that make a single mixed color source apear the same as a cross fade between two fixed color sources - I wonder if this is in anyone's R&D yet.I guess you could hope that live color fades are not too hideous, but that seems dangerous as well.
It is an interesting read, however I wonder if the study took into account the idea that if you were to swap to an all LED rig, your hang probably wouldn't include as many instruments. If you have 3 colors of par back light currently, it's unlikely that you're going to hang 3 LED pars for each area. I could see two systems still, so you could mark your colors and not need live moves, but I'd think that on the whole you'd be able to cut a decent amount of lights from the plot if you transitioned to an all LED theatre.
