Australian website Cycling Tips have a video and article with comments about doing a Ramp test on the Wattbike. There is some interesting information there. We will soon be launching our Training centre which will include information on testing and training, it will include all the formulae mentioned as well as information about how to do the tests safely.

Note: we do not recommend a ramp test unless you are already at a high level of fitness and should discuss this with a physiologist and your Doctor prior to undertaking any maximal intensity test.
