I think this is where you are making a mistake. If we define ratio as input:output, then your example case is 2:1 whether the compressor is feedback or feedforward. If we define as output:input then it's 1:2 whether the compressor is feedback or feedforward and frankly that's essentially just a different notational choice (swap the two numbers).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.
How you compute the actual gain (or gain differentials in case of feedback design) in the actual sidechain to obtain the desired ratio varies depending on whether it's a feedforward or a feedback design, but the ratio is what it is, whatever the design of the compressor.
Ok, now you're not being intellectually honest.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.
