Showing 3.5Mb/s sec over a T1 ???

For some reason in netflow analyzer sometimes i show over 3Mbits/s over a T1 connection, but when i do "show int s0/1" (the same interface) it shows the 5 min. average as 1.3MB's. I'm trying to figure out why its showing much more bandwidth at times than is actually going threw. Any Ideas?
