I'm at photozone review website browsing through lenses for both FX and MFT.  I see that the highest resolving FX lenses can be near the 4000 lw/ph range.  The better MFT lenses rarely even get to 2300.  Is the difference between the 2 types of lenses relative?

Not sure what you mean by relative but I certainly wouldn't call the difference real.

I think I was asking whether a "conversion formula" could be applied for comparing the relative ranking of a specific MFT lens within its peers to the ranking of a specific FX (or DX for that matter) lens within its peers.  Furthermore, I would like to understand if the performance of a number FX/DX legacy glass on thier respective sensors maintain their ranking when adapted to MFT, AND whether they outperform the current MFT lens offerings.

The discussions so far in this thread are starting to clear my understanding a bit.  A bit.

I'm currently very impressed with two unlikely Nikon lenses on my EM-5; Nikon DX 35/f1.8 & an old E 135/f2.8
