Iptables + quota patch

Hi!
We are temporary using quota patch to account out traffic.
But the reply from iptables is somewhere strange, for example, i consequently ask for current rule, and receive different --quota state, it jumps from 23964119 bytes to 28167287 and back in undefined order, however in the left column the ammount of sended bytes remains constant.
