Well, I find the opposite. From countless definitions in journals, text books etc. the ratio is the inverse of the ratio of the increase in output level given an increased input level.The whole idea of "ratio" basically makes very little sense when it comes to a feedforward design.
So once the signal enters the compression reagion it will not experience the same dynamic fluctuation anymore, the idea of the compressor as such, and what the user will experience.
So for example, if the signal fluctuates between plusminus 5 dB inside the compression region, with a ratio of 2:1 = 2, the output only fluctuates around plusminus 2.5 dB.
But this is exactly the defintion of the FEEDFORWARD compressor based on the given equations, not the feedback compressor, because in the feedforward case we relate input to output.
So therefore it makes sense to calculate the equivalent feedforward ratio because that is what the user actually hears, he/she does not hear any internal signal, but the output, and ratio relates input to output as written above.
Now from a musical perspective it might look that forward compression ratios of 1...2 are actually best, so one could believe that the rather misleading scaling for the feedback case is more practical.
