Well, let's agree to disagree on accounting policy. Maybe this best
sums it up: -

  operation time O(1)
  associated overhead O(N) (7..20)/100 * N by your figures
  associated side effect O(N) small constant.

I'm more interested in the amortized effect that an operation has on
the algorithm from which it is invoked (which is O(N)).
