i find strava power to be generously vanity sized, just like garmin calories.

If you want to look at power numbers, do yourself a huge favor a buy a power meter.

If you want to compare to other riders without a power meter, get the stravistix add in for chrome. it shows your rank and percentile for segments relative to the universe of other people who have done the same segment.

Of course you'll potentially be comparing with everything from pacelining teams to grandma out for a gentle spin, but that is the real world so there it is.
