This thread got me curious so I when out and did my first power profile test. My FTP was done a couple weeks ago. What I found was my 5s and 1' power lags quite a bit from my 5' and FTP.

5s = 1083 watts (13.02w/kg)
1' = 600 watts (7.21w/kg)
5' = 369 watts (4.44w/kg)
FT = 305 watts (3.67 w/kg)

I was happy to see the 5' power on the same row as the FT. I'll try some 1' when I am fresh to see if I can improve it. Bottom line, I am not a sprinter.
