The value of a Ramp test beside a FTP number?

If you wanted to discount the value of a FTP number coming from a Ramp test, what would be the next best value that the test yields in terms of performance makers? 5 min power? I tend to see by best 5 min MMP values with Ramp Tests. What are you seeing?

Anyone else using the Ramp test as a performance marker besides FTP?

Mean Maximal Power at Time To Exhaustion. Also known as… FTP.
