3 10-frame mediums = 2 10-frame deeps
4 8-frame mediums = 2 10-frame deeps.
Does that help? If it isn't dosage you are concerned with, then I'm not sure what your concern is.
It is, thank you. But do you put the strips on top of the bottom medium (just under the second), or do you put the strips on top of the second medium (and below the third)?
EDIT: In a moment of clarity, the thought came to me to just call the folks who make the stuff. They said the strips should go on top of the second box and below the third.
