So your claim about frost in uprights is just plain wrong with frost free uprights.

But that isnt enough to matter, much less than the energy
required to freeze the contents of the freezer in the first place
and to pump out what leaks in thru the insulation all the time.

Yes, uprights are a little less efficient than chest freezers, but
when you allow for the difficulty of access to the contents of a chest
freezer compared with an upright, there is **** all in it in practice.

Nope.

Nope, quite a bit of the time its just surface moisture on the food, not freezer burn.
