Unerrored codewords...is this strange?

Everyone's said how those numbers for unerrored/uncorrectable codewords in the bonding channel value table are irrelevant unless the values become astronomical but is it normal for one channel's value to be considerably larger than the others? In my 6120's log this is what I have:

Channel ID 2 3 6 8
Total Unerrored Codewords 1848019695 1848019904 1848019993 6142987204
Total Correctable Codewords 127 10 10 8
Total Uncorrectable Codewords 1600 1435 1348 1436

Modem's "favorite" channel is 2 so that's not it (though why are the 'correctable codewords' higher on that channel than the others?). Is this something to be concerned about (I do get T3s/T4s from time to time) or don't worry about it?

I don't remember if an "Official Answer" was given, but I know the topic of one channel having "priority" was discussed in length in the following thread.

»Modem developing an affinity for 1 of 4 downstream channels

If you have not done so, you may want to read that over and see if it answers your question.

Yes, it's pretty typical to see a channel with more uncorrectables than others. Your uncorrectables are miniscule, you can safely ignore it.

Also, a particular channel / frequency may suffer from more noise ingress than do others.

Your numbers are REALLY REALLY good. No worries.

Also, it looks like a Motorola modem, and they typically log 1000-2000 'uncorrectable' errors on startup as they seem to count trying to contact the CMTS and set up signals as errors. Other modems may only start counting after the connection is fully established.
