FTP from WKO chart?

Would it be possible for those of you with lots of experience with Power and WKO to give a good estimate of FTP from the following chart?  This is from a 3 hour group ride with lots of chasing riders faster than me and hammering up hills.  My last actual FTP test was indoor on the trainer about a month ago, and due to a knee injury & lots of racing, I haven't tested outside yet (sorry - my bad, I know).   Looking for a good number to use to pace a HIM next weekend (May 1).  I could also go out this Monday/Tuesday and do an outdoor FTP test.

10 watt bins:

5 watt bins:

    Perhaps you could provide a screen shot of your Mean Maximal Power Curve to show some wattage numbers per time intervals. That is what I use to guestimate.

    Beverly - I've personally never done this, but I believe the way to use WKO to estimate FTP is not to use a single workout, but to look at a similar chart which covers the last 4 weeks of your bike workouts. See this entry from the wiki.

    Usually prefer to work off of 28 days put in bins like that. However, I'd say it looks to be between about 200-210.

    Golden Cheetah has a marvellous tool to do this. Load up the rides (similar to doing it on WKO) and use their MMP plot, and it will spit out a fit that (at least for me) frighteningly close to my 42 minute EN tests.

     as said above we need to see the same shot of a 28 day chart.  I like 6 watt bins for whatever reason.  If that was a 28 day chart I would say 210.

    Unfortunately I don't have tons of power data from the last 28 days because I've been doing lots of rides with this roadie group on my road bike, which is a 9 speed, so it would be a pain to switch cassettes on the PowerTap wheel from my the usual 10 speed tri bike. However, I just got a 10 speed road bike, so problem solved. Thanks for the responses. Given that I don't have more data, I'm thinking that I'll do a test on Monday, maybe the 95% of 20min test since that will be less fatigue-inducing pre-race.

    Also, here is the mean maximal curve:
