Modified Internal Rate of Return (MIRR) accept or reject decision rule?

So what is the accept or reject decision rule for MIRR with respect to the financing and saving rate? does it even have such a rule?

I am doing a finance project for my masters degree and although I have done MIRR calculations, I am not certain how to deal with the answer. ALL BOOKS seem to talk about the limitations of IRR and how the MIRR resolves them, but is the accept or decision rule the same as with IRR? they never seem to mention that.

MIRR is not really even covered in the CFA Curriculum. Just know that this correct some of the flaws in IRR, like having multiple IRRs. Then again I took level I in 2009, so things may have changed.
