Your PP profile looks normal and, at the beginning of the ride for the first 3.5KM you do not have any ground wind.

Your ride file shows a significant tail wind starting around KM 3.6. Were you riding in the draft of another bike?

Where your watts drop at KM 7.4, you are actually on a downhill -1% grade and in an 8KM/h tail wind.

You'll not that the tail wind is quite variable.

Also, there is variation in your cadence. Even a momentary reduction in cadence will cause watts to drop quickly

I think your PP is working correctly.

still find it hard to beleive i can hit that speed at even -1 % with a very very minor 8k tailwind and 80 watts!! and no i was never drafting .. also tonight i noticed if i pedal very slowly ( freewheel still clicking) i can get up to 30 watts when coasting yet if i stop pedaling it drops to zero ,,,,

Actually, at this point of your ride your tailwind is quite significant.

By any chance is this on a rougher road? If so, new FW just released will provide better results.
