Are the scoops that come with powder accurate?

I got some powder from WG and OE. They both came with measuring scoops.

The little side says 5-10mg and the larger size says 25-35mg. Are these at all accurate within that range? Has anyone weighed these scoops, do they come in under or over?

Waiting on my amazon scales to arrive so it's all I have right now. These powders just don't seem to be hitting like 18mg tabs do so im wondering if im just under dosing using this scoop.
