Whykoff was a value investor?

Hello, greetings to the community. These last days I have been looking for information about the whykoff method, his books, his tape readings and other books such as “The whykoff Methodology in depth” I have seen whykoff mention the intrinsic value of a stock many times as a value investor or something similar. I am also studying that with the discount of free cash flows Does anyone know if the Whykoff methodology can be combined with value investing?
