100%, and this is something I've been saying in response to the discussion about Link Teams vs. TAGs. If you plot each one's active turn effectiveness (y axis) against damage taken (x axis) you receive two very different functions. The TAG follows a linear function - its effectiveness doesn't change as a result of damage taken until it's Unconscious. And, as you said, you can bring it back from being doubled out fairly easily. The Link Team follows a nonlinear function. The first team member that goes down drops you from +3 BS to base, and if that team member is packing the team's only SWC weapon, then it's a huge punch. The function plateaus at the second casualty, ignoring weapons. The third casualty pops the team's effectiveness down to that of an individual trooper. Almost across the board, Wounds are easier to remove from infantry than they are to remove from TAGs.
It's worth noting that losing link team members also make it even easier to damage it further. But that's probably what was meant by its effectiveness being non-linear function. But back on topic, I don't think that Uhlan's perceived problems have anything to do with how he compares to things that are very different in nature.
I just have to point out that a tag has a constant performance, not a linear one. A linear equations Y = mx + c For this to be true fpr tags m =0 which means it cannot be utilized in linear algebra as it is already its own output and cannot be placed in matrix form. Similar link teams are not, non-linear, they are heavieside functions with discontinuity in performance at the loss of a link member. One day ill get round to the writeup on the math behind infinity beyond the statistical analysis. As to how you compare the two i imagine a step wise intergration of the area under the curves would be the best way to do it
