I guess with a very small tank this will also vary - at some point
the wall thickness will be set by mechanical "minimum gauge" issues
(rather than scaling with the volume for a given pressure rating),
resulting in an increase (relative to the net tank volume) of the
boiloff requirement for chill-down.

My experience is a bit less than 2X but it depends on the mass (pressure

Folks at the Cape once told me it takes 2x the volume of the tank to
fill a large ambient aluminum tank with Lox; basically, one tank
volume is required to cool it.
Given your material and insulation I concur that a spreadsheet model is
appropriate but that model should not come in with anything above a 2x
result, given the above.
