This page is grossly misnamed -- it is Vertical Ascending, not Velocity, but there's no good way to rename a page.
The Relative Power formula seems incorrect. As written, assuming you hold vertical speed constant, as the grade steepens power declines, quite dramatically. 50.193.56.98 ( talk) 02:49, 24 February 2015 (UTC)
Changed two wrong statements in "Background". From: "Ferrari also stated that every one percent increase in average gradient decreases VAM by 50. For example, a 1700 VAM on a climb of 8 percent average grade is a performance equivalent to a VAM of 1650 on 9 percent average grade" to: "Ferrari also stated that VAM values exponentially rise up with every gradient increase. For example, a 1180 VAM of a 64 kg rider on a 5% gradient is equivalent to a VAM of 1400 m/h on a 10 % or a VAM of 1675 m/h on a 13% gradient." The VAM is obviously higher on a steeper climb, otherwise you would climb fastest on a flat road (where you actually don't climb at all). VAM also doesn't increase linearly with the gradient and certainly not by the same constant factor for every rider (regardless of weight and power output).

Hello, cycling enthusiasts. I am not familiar with your topic; I came here through an error report. I fixed the issue with the error after going through the editing history on the page (a source was entered with no details 03/13/2020, so I don't think it was ever valid).
During my review of the editing history I found a source that had been removed.
https://pubmed.ncbi.nlm.nih.gov/28121252/
I don't know if anyone feels it needs to be incorporated in the article, but since I don't imagine many will be of a mind to go through the page's editing history to discover it, I wanted to list it here for anyone who thinks it has information relevant to the article's topic.
