Hi D, Thanks!
I saw at the outset that the testers used the most extreme cycle on each machine to give the strongest test possible, but now, your explanation makes it clear. Likewise, a US machine on a pre-wash with extra rinse, or a Whirlpool on "Super wash" with an extra rinse would take almost an hour. The best thing was you helped us understand is that most UK users used a 40 minute cycle. Otherwise, washday, at 2 hours a pop, would have taken forever ;->
I'm still grinning, though, about the Frigidaire not getting out the wine and cocoa as well as the other machines did, and I have a theory, but it's gonna take me a while to write it.
