under the graph you see MAX and AVERAGE values.  If the MAX is 30.6
kilobytes per second and this is 95.5 percent, then each percent is
about 0.32 kilobytes per second.  100% is thus 32 kilobytes per second.
The average is 26.4 kilobytes per second and 82.3 percent: each percent
is again approximately 0.32 kilobytes per second.

I don't see your problem, everything seems to be correct to me.  If
you think your line speed is 256 kiloBYTEs per second, just change
the MaxBytes setting to match that number.  You'll see that each
percentage is divided by eight in that case.  Just make sure it
really is 256 kB and not 256 kb when you do this.
