No. 1g OAV was compared to 1g 3X OAV, a brood break, a brood break with 1g
OAV, and a brood break with 1g 3X OAV. There was also a positive and a
negative control. Apivar was the positive control.

The goal of the study was not to compare OAV to Apivar. But to compare
different types of OAV methods in accordance with its label.

They presumed nothing. A 1g dose is in accordance with the approved label:

VAPORIZER METHOD: Apply only to outdoor colonies with a restricted lower
hive entrance. Seal all upper hive entrances and cracks with tape to avoid
escape of Oxalic Acid vapor. Smoke bees up from the bottom board, *Place
1.0 g Oxalic Acid Dihydrate powder into vaporizer.* Follow the vaporizer
manufacturer’s directions for use. Insert the vaporizer apparatus through
the bottom entrance. Apply heat until all Oxalic Acid has sublimated.

The dose isn't a recommendation. It's the instructions in accordance with
the label. It's illegal to administer OA against its label. The label says
to use 1.0G Oxalic Acid. The study did what the label says.
