Burnishing can make a huge difference. When I had an EXT fork, the last 1/3 of travel was unusable. I sent it in to them and they checked the bushings (which were supposedly done at the factory) and found that the left lower one was very tight. After that I could get full travel if I ran low enough pressure. Similar story on 1 of the 2 Zebs I have (one came to me already burnished by Diaz, the other was brand new) - burnishing gave me about 10-15mm more usable travel.
The great thing is aside from the tool being a bit pricey, it's simple enough that any fork service shop should be able to do it, and it can be done alongside a basic lower service.
