Yes of course, part of this intuition is using data from these software, TT or race efforts, even chasing a KOM (If its a threshold-is effort) all can be used to inform your perception of ftp.
It’s definitely not like the 20 minute tests gives us all a perfect result - we all know this isn’t the case, Kolie Moore’s test doesn’t do this either - But we can use this data to inform our perceptions and the sensations we feel of riding at our FTP.
I’d like to hear more opinions though - maybe I am wrong - maybe perception isn’t enough and some test is going to give me a more accurate number - Kolie Moore definitely cuts it closer than Ramp Test for sure in this case.
