Hi,

The plugin uses the same values as iwconfig, however it just combines
them in to one number.

When iwconfig displays 78/100 it is showing value/maximum. The
assumption
is that this is a linear scale. However the plugin uses logarithms
rather than a straight percentage calculation, hence the "strange"
values. I am not sure why this is the case as it predates me. I guess
as most will just assume that it is a simple percentage we could
just change it to that.

If no-one objects to having their wireless signal strength reduced
then I will release a new version when the FreeBSD fixes have been
finalised, provided that doesn't take too long.

Thanks,

James
