To Fee or not to Fee

This might help. I've excluded all the txs that were included in the next block, since most of them were.

The analysis to do is on no-fee transactions that have a priority > 57.6M. Compare with the times of those < 57.6M which include exactly the minimum per int(KB+1) fee. These are the default sending modes of Bitcoin-qt with no optional fee.

My hypothesis is that Bitcoin's default behaviour creates two classes of transactions, where the "preferred/non-spammy" class actually gets a lower quality of service from miners.
