The paper details how they measured egg size. Shouldn't be difficult to
see under a scope.

Only in one dimension. Queen cells vary greatly in length, and the nurses
can't probe the depth of the jelly in the cup.
So do the basic math. The difference in area between a 9.5 mm and 10 mm
cell cup (the only part typically containing jelly, is only 10%. But the
resulting queens were 25% heavier. The basic math doesn't make sense.

Thanks Gene, in this case I wasn't confused, and measured carefully with a
micrometer.
