The bee will still release the 400 ppb syrup to the  proventriculus
regardless of what she is doing. It is all a matter of time. And the 400
ppb, or any other abnormally high concentration, is the issue. The
researcher asks us to accept the rationale of using such high
concentrations because of distribution, which seems to be assumed as even.

I know of no way to insure a reduced dose based on the number of bees as
the feeders will take on the full 400 ppb. For the Harvard study to have
any validity, it has to show what the actual dose is for an individual bee,
as was done in the RFID studies.
