[mrtg] MRTG byte measurement and scale

Hi,

I've been using MRTG for a few months now and there's 2 things that I can't
seem to get right with the throughput graphs on the cisco routers I monitor
: 
Monitoring a typical 64k leased line, the bytes per second reads 0.0k to
9.6K sometimes goes up to 9.6K ! I'd like to make the bytes axis fixed at
64K and find out why my scale is so inaccurate, even if I multiply by 10
its showing 32k above what the line speed should be capable of. 

Target[10.20.2.250.2]: 2:PUBLIC at 10.20.2.250
MaxBytes[10.20.2.250.2]: 64000
Title[10.20.2.250.2]: HQ (): Serial0/0
PageTop[10.20.2.250.2]: <H1>Traffic Analysis for Serial0/0
 </H1>
 <TABLE>
   <TR><TD>System:</TD><TD>CRH_HQ </TD></TR>
   <TR><TD>Maintainer:</TD><TD></TD></TR>
   <TR><TD>Interface:</TD><TD>Serial0/0 (2)</TD></TR>
   <TR><TD>IP:</TD><TD> ()</TD></TR>
   <TR><TD>Max Speed:</TD>
       <TD>64.0 kBytes/s (frame-relay)</TD></TR>
  </TABLE>

Any suggestion appreciated.

Mike.
