This is interesting... I decided to run some of my own tests.  I did a 
capture of ~10k packets with a single RX chain and I see the same issue.

I used a decimation rate of 64, and therefore the timestamps on the 
recorded packets should be 64*126samples=8064 ticks apart.

I recorded 8 timestamp jumps of the following sizes:
10264763
1003
985
5569
1738245
1003
987
5557

Very odd, but there's got to be something that explains it :)  I'm 
looking in to this now.
