Contradictory bandwidth reports in overlapping extra-info descriptors
On a randomly sampled day in July there were 2000+ cases where the bw reported by extra-info for a given timeslice on a router was two different measurements, depending on which extra-info descriptor you looked at.
Here is an example in the read history for relay Pounet27TorRelay:

The difference starts after the zeros in the following sequence in each extra-info:
21:46: 11229184,13546496,11268096,13392896,16567296,9265152,6163456,4869120,8190976,0,0,0,0,0,0,0,0,0,245760,4738048 04:46: 11229184,13546496,11268096,13392896,16567296,9265152,6163456,4869120,8190976,0,0,0,0,0,0,0,0,0,734208,439296
I need to characterize the samples I have better to see if there's a pattern but any idea why this might happen?
