at home ive kept a log since the beginning, im in the 1800 now (logged, almost 1900), 1000 of those in my klippermate-DW machine! (I think I got down to like 25 minutes on it), last 3, 4 years in my new2me prince-5000!! I picked it up as "sports-authority" was closing their store near me
at work its provably another 1000-2000 by now, I don't know there,, total guess..
the electronic machine helps, but proper technique fanning/weaving/tying knots, etc etc helped me most...
