Really, the impact of incorrect adjudications is larger than it seems because of TB hits during engine search? Why don't you spare a second or two thinking about what's actually being discussed, as opposed to the tangent you want to discuss?
Arasan's "loss" of 0.5 points almost caused it to lose 22nd place in the tcec-9 Rapid. Fortunately, it had the S-B tiebreaker. Trivial yes, but consider the "adjudication bug" in tcec-9 could have caused an engine not to advance to the next round, or the wrong engine to become champion.
One other comment. The 2 games that required more than 50 moves to checkmate had identical pieces but with colors reversed: KQkbb and KBBkq. Depending on the placement of the pieces, the checkmate would take about 75 moves (based on Ferdinand's previous post, if I understand it correctly).
