Hey Paul,
I run ErgDB and have been looking into this. There are three ways I'm
looking at. The first is the easiest to do.
1) Select time segments for RPE like the Sufferfest does. You could
do something like 5 minutes at RPE 7, 3 at RPE 9 (hill), 1 at RPE 4
(downhill), etc. You'd just go through the video and compare the
power data.
2) Look at data from the ride and generate it. If you can email me
your file from WKO and your FTP, it can give me a good starting point
3) From GPS with elevation. This is useful if you don't have a
powermeter on the ride. This would be similar to converting a .crs
file to .erg (which is a feature request in GC). I can also generate
a Google Earth Tour, which is the poor man's Erg Video. I just need
feedback from people on conversion from slope to FTP % (I may go with
RPE instead).
