I believe the 2 represented is just a constant that whoever came up with. typically you take your reference at the the node are first active. I never count the reference in the cascade in other words its 0. Depending on your formula (lets just use the n/2+1.5= Min/Max) that would mean your 1st in cascade couldn't be greater than 2.0 and so on. Every where I have been the spec on return was constant nothing greater than 3db with no greater than a .5 delta even EOL's which sometimes was hard.
The bottom line is get your specs and roll with it. Sometimes trims have to be used the important thing is to know what your looking at, Suckouts, reflections and so forth. If it fails, fail it are fix it.
Hope this helps
