So for me it looks like a circa 7% difference in FTP measured at crank vs. hub. Sound about right? Maybe I should clean my chain...

hmm - sounds a bit high.

Although need to take into account error ranges for both devices. Typically + - 2 % for crank and + - 1% for powertap iirc, so that could account for %3 of that (or it could be 10%)
