From past experience the plants growing upside down do not tend to do as well as those grown the traditional method,
roots will always seek to bury themselves further into the ground, and all the roots in my planting were crowding the bottom of the containers.

true..we had big upside down plants with no produce.

I agree. Gravity reigns supreme. My wife keeps insisting on an upside-down tomato plant or two every year. Last year we had a one digit crop - that digit being zero.

Had very bad performance form two TopsyTurvey’s. The same variety plant planted in the ground gave 5x the fruit.

Starting the root ball high up in the container would give the roots lots of room to spread, wouldn't it?

Tried this last summer. It was an utter failure.

It may have been the weather, but tomatoes plants stayed small and some tomatoes grew but never matured.
