I was just passing along a study presented at a nanog meeting about
this kind of topic... I really do like to know next to nothing about
peering.

sure, there are more variables (I gather) than just bits in/out...
like 'but my customers complain more if you are further
away/slower/more-lossy' etc. None of those factors are in peering
agreements I would bet, though clearly ratios are, so that stick is
used to whack the other-guy over the head.

web traffic (as a measure) seems to be ~10:1 when I look at my
interface at home (vz-consumer-type), without packet-loss and over a
decent sample of time. As with all of the 'peering disputes' over the
last few years, it'll be a fun ride to watch from the outside :)
