When doing Ramp Test today, I reached my fail point and stopped pedalling ca 15 secs after I entered 480W "minute". So my strongest 60 secs should be around 463-466. However it turned out that average of my strongest 60 secs was measured as only 458W. Not a huge difference, but when analyzing data - - Watts during last 15 secs were lower than Watts during second last minute... So basically last 15 secs were "ignored".
