I normally estimate my FTP by the 20 min avg power *0.95 method. The 20 min TT is done as last part of the 1*5 min, 2*1 min, 3*20 sec, 1x20 min power profiling out of Hunter´s book. Out of this test I recently got 6,2 W/kg out of the 5 min test and 4,9 W/kg out of the 20 min test. The 1 min and 5 s results are rather modest. Since the 5 min result is in the upper part of the chart, I wonder how much the anaerobic component skews the calculation of my FTP. If I understand right what was written in this forum the 20 min test tends to overestimate FTB for people with a high AWC. Is this still true after the whole set of tests done before as I surely will be able to produce a higher 20 min avg if I only do this test alone? I know that I could test this by longer L4 intervalls but I don´t want to dothem at this time.
