I'm new to this so I'm just guessing... on Garmin Connect they have a Power Curve that gives you historical points of data for specific time periods. For me:
1 minute - 331w
20 minutes - 200w
60 minutes - 162w
Only the 20 minute time was a deliberate test (outdoors with a few minor interruptions) but it looks like the longer I go the worse I look on paper. I'm thinking my real FTP is not 95% of 200.
edit - I may have stopped for a beer during those 60 minutes so I may be selling myself short! I guess I need an indoor trainer if I'm going to get serious about this. I have a 20 mile bike leg in a race next Saturday so that will be informative too.
