When doing mixed loads
Some textiles such as those made with Lycra, knits or others should not be subjected to long periods of high final spin speeds and or in the spin dryer. When first got my Laundry Alternative spinner soon found that out. T-shirts, undergarments, etc.. all stretched out of shape.
Thing hate about all domestic spin dryers is that the opening is rather small and thus loading large items like table or bed linens can pose a problem, more so if you are trying to avoid an unbalanced situation. At least the spinners on Easy Twin tubs like many commercial hydro-extractors have that center cone to assist in spreading things around sides of tub.
"stop the SQ FL after the first surge of the final spin, wait until the door unlocks, then load the stuff into one of the Mieles for a final spin."
Have been doing the same lately with the older Miele to save work on the old girl. Just take things out either after draining final rinse water or first pulse spin of finial series; then bung them into the spin dryer.
It is amazing that the spin dryer will get things done in <five minutes while the Miele or AEG takes ten or so. This is mostly because the final spins on washers are a series of pulse, or short full spins then stop to redistribute, then proceeding to the final full speed spin.
Thing to also note that even on many European front loaders the higher spin speeds (1600, 1800) are only for the final few minutes of overall spin cycle. This is why for some fabrics you *may* get more water extracted by putting the load into a spin dryer after coming out of the wash.
This is a very good article from a UK site about final spin speeds.

As you can see the laws of diminishing returns kicks in pretty quickly. The differences between water retention between 1400 and 2000 rpms is not that great and nearly nil from 1600 to 1800 rpms.
Then you have those who believe lower spin speeds are better for washing machines overall.

There might be some truth to this in that in Europe you can find plenty of "vintage" front loaders whose final spin speeds were no higher than say 800 rpms still chugging along.
