- This is my bet. Presumably he did that to account for the 0.95 multiplier used to de-rate a 20-minute FTP test block to estimate the FTP. Essentially, he reversed the math to set a target and added 1% for extra measure.
As we’ve covered in many topics here, that theory is fine but flawed and should not be taken as a blanket validation or disproof of the accuracy of AIFTPD. Many factors are present and it’s not necessarily worth diving into that in this specific topic. It’s better in the main AIFTPD topic or the others where people have attempted test comparisons like this.
