[rrd-users] This isn't normalization

OK, I'm using Cacti, but the problem seems to be in rrdtool, or rather
I'm not passing the right information. I'm monitoring how much
bandwidth is available on a metered connection. When the graph hits 0,
I'm out (and throttled). Simple stuff.
The problem. I have maximum 15GB per month of "anytime" data and 20GB
of "nighttime". The graph is telling me that I have 14.95GB remaining
in the former and 20.38GB in the latter. Now, how could it possibly be
giving me a value that is MORE than the greatest value being fed to it.
I am using GAUGE/LAST for everything.
Here is a clip from rrdtool info. How do I use the last_ds values?
Those are the correct values. Thats what I want graphed. Thats what I
want to display. I have no idea what the value lines are or what they
are so much larger than the real values (larger than the max). I don't
see how normalization could inflate values. Any help would be GREATLY
ds[anytime].type = "GAUGE"
ds[anytime].minimal_heartbeat = 300
ds[anytime].min = 0.0000000000e+00
ds[anytime].max = 1.5000000000e+07
ds[anytime].last_ds = "14600000"
ds[anytime].value = 2.9200000000e+07
ds[anytime].unknown_sec = 0
ds[offtime].index = 1
ds[offtime].type = "GAUGE"
ds[offtime].minimal_heartbeat = 300
ds[offtime].min = 0.0000000000e+00
ds[offtime].max = 2.0000000000e+07
ds[offtime].last_ds = "19900000"
ds[offtime].value = 3.9800000000e+07
ds[offtime].unknown_sec = 0
