JIM-- I think they test washers using the Normal cycle because that's the "go-to" cycle for most people. It's also the one the energy use ratings are based on. I've stated a couple of times that the normal cycle on my Frigidaire has too short a wash period for the size of load it can handle. I always use the Max Soil level option, which boosts the wash time on the normal cycle from 15 to 21 minutes, and the heavy cycle from 20 to 26 minutes. In fact, I use the Max Soil level for all cycles (although you can't select that with the Delicates cycle).
The giant loads of highly-stained kitchen whites get the Sanitize cycle, which tumbles the clothes in detergent for about an hour, boosting the temperature up to 152 degrees from a lukewarm fill. It's provides a great profile wash, and has yet to leave even a trace of a stain behind. The cycle, at Max Soil setting with an extra rinse (I use liquid chlorine bleach) is 1:47. It has dawned on me that I could drop the soil setting to Extra Light and save 12 minutes on the cycle, but I haven't changed the setting, yet.
The Anti-Static option on the dryer eliminates the need to use fabric softener. The air in my house is bone dry this time of year due to the forced-air heating system. Since buying the new washer and dryer, I haven't once used any type of fabric softener. When drying loads of dress shirts and pants, I choose the Add Steam option plus the Anti-Static option. An item or two will emerge with sizeable damp spots when using the Anti-Static option, but those spots dry quickly and have never left a water mark on my mostly solid-color shirts. But there is absolutely no static cling. I dry big "permanent press" tablecloths, which used to generate static in the winter even when using fabric softener. Not a bit of static with the new dryer, and again, no fabric softener.
Although I run a Clean Washer cycle when it prompts me to (every 50 cycles), I've heard enough stories of waxy, stinky build-up in ultra-low water use machines that I just decided not to use softener any more. And due to similar build-up stories about dryers---clogged filters, etc., I figured it would be best not to dry clothes with softener residue. And I'm saving some $$ by not having to buy Downy, anymore.
LAUNDROMAT-- Spin direction: I actually had to go downstairs and run a spin only cycle to find out, LOL! The answer: Counter-clockwise. Funny, though---had I not checked, I could have guessed it was clockwise.
