Hi,
Visibility by scale is controlled with MAXSCALEDENOM and MINSCALEDENOM at LAYER
level. Pretty easy. I am never trying to calculate at which scale the change
happens, it is much faster just to try and check the behaviour with a WMS
client. For example, for rendering a layer between nominal scales 1:10 and
1:100 use
LAYER
...
MAXSCALEDENOM 100
MINSCALEDENOM 10
...
