Doug, I am very surprised. I noticed and improvement with square on both my saws, but especially the 044 (just got the 046). When cutting with my nephew (MechanicMatt) and my brother, (a 76 cc Husky and Stihl 460), I gave them loops of square so they would not be "left behind" by my 044. They have both kept the square file on their saws, and I had to buy more of it.
I think the Madsen's website is pretty accurate. They state that full chisel is about 10-15% faster than semi chisel, and square file is about 10-15% faster than round file. There must be a reason it is so popular in the PNW on the big trees. I like the performance on hardwood, but it just rips through softwood.
