After reading every article in the list from the above lab I learned a couple of things:
"Down testing has changed in the last 10 years". Meaning that as we surmised, the new high loft down may just be the same old down measured differently.
The USA system is cubic inches per ounce - with absolutely no reference to how it is measured, compression, weighted piston etc, except that it may be steamed and fluffed prior to testing.
There are many international volume measurement satndards, like different shoe size standards, which may be compared using a table.
NO WHERE IN ANY OF THEIR INFORMATION WAS THERE A DEFINITION OF HOW THE LOFT IS ACTUALLY MEASURED.
so stuff it, the down I mean.
