Note that the cheap model has a detergent "cup," a slanted-out at the top, tapering toward the bottom, plastic half funnel where the detergent was poured and even though the cheap model has as many water changes as the upper model, the detergent was LONG GONE by the main wash. I wonder if it would have washed better if they skipped the water changes and did a 25 minute wash with the Calrod running. Might not have been sufficient water changes to get rid of the heavy soil. Note, too, how the pot smasher cycle made the first after rinse part of the wash cycle to give an 18 minute wash. Hotpoint-made machines had a Pots & Pans cycle also, but it was the same as the regular cycle without a dry period.
