LL, you may not need to bother with the extra spin. SQ washers do spin on the slow side. I think our Amana (SQ clone) had a top spin speed of 625 RPM. Yours might be 725. Spinning for a longer period may not help much. In theory, you could spin it all day at 725 but extraction won't surpass 725RPM worth.
Maybe this is why SQ's dryers don't mess around.
