When the first difference is positive, the history is trimmed. This is the only time any kind of O(N) or O(log2(N)) operation is performed. First difference positive implies that a new local maximum is achieved: in this case, all of the most recent history samples that are less than the new maximum are trimmed.
Correction:
[The new local maximum dominates all history up to the most recent *history sample* that exceeds it, which is retained.]
I had said "most recent local maximum" but the history contains a monotonic non-increasing sequence.
