The charts don't go far enough!

Options
Hi! Does anyone know any reliable fitness/assessment charts for WOMEN over 65 (UK based)?

Those charts that I can find seem to stop at "over 40" or "over 50" and, without being too conceited, I really do not believe that the AVERAGE woman of my age is fitter/faster/lighter/stronger than I am. I would like some empirical evidence against which to measure my fitness levels and improvement.

Many thanks if anyone can come up with some sensible suggestions.
