Analysis:

Some of these trades are ancient. People are willing to let their trades be active for months at a time, accruing all sorts of offers in the meantime (mostly a ton of lowballs). I've stuck to the most recent offers and tried not to put repeat offers in multiple trades.

All but link #4 have offers at 1.2 buds, plus it sold for that amount in link #10, hence the low point being there. There was a 50 key offerer who seemed really unsure of himself and likely retracted it, so I'm tossing that out. Setting the high at 1.6 buds since it sold for that in link #9 and some of the offers in the active trades are approaching that number.
