I share your observations--I've had stellar loads in my 1-18 that I couldn't believe, and some real sucksters that I thought would be easy. The key, as you say, is understanding the load composition and setting the water level (and time!) accordingly. Even when I load properly, I sometimes find that dress shirts and slacks get tied together, or bedsheets require unspooling before loading in the dryer. C'est la vie.
Because this requires thought, I think it was doomed
My mother's BD Kenmore from the early eighties was very much fire-and-forget in terms of getting everything in there.
Good detergent seems key in a 1-18 too, since some get way too sudsy and then you end up with a blanket of fine lint settling back on your clothes when it spins out the water, once the suds are compressed back against them.
