Cool, thanks. Interestingly, for the whole 72min my average was higher than my 60min... I guess that makes sense, going harder at the beginning and end must've bumped the total average up. Think I'll stick with 240w for now and see how that feels training.
Over the winter I do 20 minute efforts on track, and then apply the 5% reduction. Over the summer I use the results from my 25 mile TTs. I don't often get below the hour mark (twice so far) so I can get a 60 min figure from those.

How does everyone else here estimate their ftp?
