The ability of a transponder to handle a high reply rate will become more

Let's assume that a [mode c] transponder is being interrogated at a rate
higher than that at which it can respond. Does this matter? If the
transponder is responding as quickly as it can (let's pick a hypothetic
10/second), while it is receiving [a hypothetic] 20 interrogations/second,
won't each interrogator still see the 10 responses per second and
therefore "see" responses to its own interrogations?

Or is there some unique mapping from a specific interrogation to the
specific reply?
