wade, I think you have learned what I have learned. Even when she's wrong, she's right. Just say "Yes, dear, I measured wrong."
On the upside, even though you have 2x the water specified, since it is being used only as a leveler over an existing concrete floor, the weakness that results is not very important. Once you get the linoleum over it, it should be fine. Just be careful not to gouge it before then, as it will be kind of soft.
