There's a hole in my bucket dear birdbrain, dear birdbrain. The OP was
complaining about the variable thickness of 80gsm paper which suggests
the density of the sheets - and hence the thickness - is variable.

It does vary, for example, some paper has a coating on it to stop ink
wicking along the fibres and that is denser than the paper base.

Then the actual base can vary with the type of fibres used.
