UniChris is ignoring rather simple physics. The easiest way to minimize time to distance is to go hardest when you are going the slowest and easiest when going fastest. Easy/hard is relative. It might be +/- 10-15% off FTP.
Ohhhhh, oops. Well, a hair under 50min for me. I was under race weight at the time and had just finished my A-race TT prep and race. So fitness was also optimal. I didn't realize for some reason it was just 3 to 5min hill. Yeah, that's ummmm just "to the wall" the whole time. I still wouldn't pace it too over or under though if you know what your 5min power is.
Curiosity, how did you get to the W' figure? My inquiring mind would like to learn more how to do that math.
