This could be a situation where you ski it and leave it alone. Then cover it with a tarp in the spring.The tiller is just there to make pretty lines. The actual skiable surface comes from the blade, and if one doesn't use that there is no amount of tilling that can fix a trail. I agree with your Pennsylvania example. After a heavy thaw/freeze it should take at a minimum three passes to fix the surface. The first one I don't even have the tiller down, I just rip up the ice layer completely. The second, and third if need be, is to break up the big chunks with tracks and blade and rearrange my huge windrows back across the trail. The last one is the final till where I am just pushing enough snow to make it level again, and by then it has been broken up enough that it tills out clean.
Unfortunately this requires a deep base to do properly, because you're cutting off probably eight inches of surface at least and ice can easily grab the blade and force it even further down. On a frozen surface blading is really all or nothing, you can't just shave off part of the ice. It has a tendency to catch the blade, especially the wing, and dig a hole that the tiller is not carrying enough snow to fill in, so you have to go find more snow, except you don't really have easily accessible snow because it's frozen solid and you don't have the depth to go digging, and if you do it creates holes that are hard to fill in, etc. If you don't have the depth to be confident in plowing it heavily it's very hard to create a surface with enough loose snow for the tiller to work with.
Edit: I do not work at Sugarbush, so I have no idea exactly what they were dealing with; my comments are in general.
