I would say yes with one caveat, If you need -71 to get full modulation and need to guarantee that it holds like in a PTP link then you would want additional fade margin. Assuming an additional 10db would mean you would want -61 minimum. A PTMP network may or may not need that kind margin and could use less power.
Ideally one only uses enough power to acheive the required levels to make the link plus some margin. Anything over that is just polluting your own rf space.
