Default width to power ratio on props

most plans of building your own propellor omit the graphs needed to calculate the width to power ratio .. i got the calculus from nasa but why plans omit this is an amusement to me and so i have to make my propellors slightly bigger then cut them back until i get the revs desired .. such is life .. even though i pay for the plans .. any one can calculate the diametre and the pitch but what is needed is not a simple answer the aspect ratio of seven this implies the desighhner dosent know then why say i can buils a propellor from the plans when i simply cant they are indefiffient ..
