It's not like any of us are asking for the specific material information, wire diameter, coil diameter, and active coil count that they used to get to whatever rate. Even for a little after the fact trimming, it's still not necessary to know all of that (even though at that point one could make all of the necessary measurements).
As far as the notion of "matched package" goes, if they don't describe what their basis for calling it "matched" happens to be, even that is not tremendously useful information (matched for what? best ride at 35 mph? best ride at 85 mph? autocross? drifting? car fully loaded? driver only?)
