Add NERP to Free-Agent Data?

This probably has been mentioned before on the boards, but in case it hasn’t: how difficult would it be to add NERP (or whichever field wiser players than me might recommend) to sortable player data? I’m guessing “very.”

NERP seems like it’s more predictive of card performance than any of our current sortable fields, such as OPS.

Although repairing pricing errors is of course the priority — because that would level the playing field considerably, stimulate the use of neglected cards, etc. — perhaps adding something like NERP, if not too onerous, might flatten the playing field a tiny bit?

Thoughts? /

Or add it to the spreadsheet data on Diamonddope??
