Normalized Pace Data Field

I would like to be able to see either NGP (like Training Peaks) or GAP (like Strava) as a data field. I realize those exact algorithms are probably protected. But something like that.

Additionally it would be nice to support altitude and temperature normalization. I know Jack Daniels has formulas/tables for those. But again I think they are copyright. But there may be other public corrections that are available.

Bonus points if you do temperature normalization, and support a Tempe on a 920XT.
