Slowing down for a spin rinse is not something I'm a fan of.
Our previous Simpson TL did this, as well as a very slow initial spin after pumping out, and pumping at a standstill for several minutes. It would slow down (slowly, without use of any tub brake), spray the water, which usually landed in the bottom of the tub, not on the clothes (unless you stopped and redistributed them), then faff around for another couple of minutes trying to get back into the spin routine.
The last 3-4 rinses it actually powered up very quickly, and made a nice sound. But the first 3-4 were "tedious," to say the least.
We ended up just defaulting to a single deep rinse, instead of the 7-sprays programme it had. The deep rinse was far more effective, even if it did use more water.
