If your updates have an offset to your cdp's then the values will be interpoated. Check the contents of your rrd with rrdtool dump.
Also, you might be storing your values them as counters i.s.o. as gauges.

I'm using freeBSD 4.5 and snmpget to get the required information I want.

As this is driving me crazy.
