I am intrigued by the Ganch Calculator and have been messing around with it the past few days. If I did it right, the following lines would covert to the following money lines. For example a 4 pt favorite would equate to a ML fair value of 192. If you had a 4 pt fav and the ML was -185 then the Fav's ML is a solid play. All NFL lines are considered evenly weighted (i.e. -105 each side or -110 each side depending on your book's juice). I got the results below by putting in the line and then putting 100 in both the fav and dog boxes. I then scrolled to zero to get the corresponding ML. Hopefully Ganch will lend some insight here.
