Thanks, wow you're on top of things! I've been experimenting with different ways of normalizing prices to take into account banked/stripped points, seller-paid closing costs, and seller-paid dues. Currently the normalized price is one which equates the initial cost with the PV of "cash flows" generated by the points (Points * solved-for $/Pt) and annual dues. I assume 45 days to close, discount rate of 5%, closing costs of $750, banked points with less than 7 months to expiry are only worth 50% of their value, and less than 4 months are given no value. The value of banked points close to expiration is probably the most important assumptions in terms of rearranging the results and something I'm still working on. I have figures that get adjusted even further for use year and contract size which I may move to, but it needs more analysis. I think the next step is to provide more clarity on the website around how they are ranked. That will lend itself to a tool for people to evaluate their own offers against the historical sales. Also to caveat, I do suspect some of the data was not entered correctly as well (e.g., not including all costs in final price), but I haven't dug in too much yet.
