This is good information to know. When I first got my Janome 11000, I did a bunch of practice machine embroidery blocks, made them into a quilt and then did a lot of FMQ on it. It was not bad at all and was actually the second queen sized quilt I had FM quilted; the first one was not too bad either. Lately, I can't do it worth a darn on the 11000 or on another machine that I have set up strictly for quilting. I've been blaming it on the machine tension, as well as my lack of practice. I guess it's just me to blame and not the machines at all.
