'With impeccable timing' is quite often heard. Sometimes it is used at face value as, for example, "The Red Arrows' display was carried out with their usual impeccable timing". On other occasions, it is used critically, for example when someone says something at the exact moment when they should not have said it. Then, others might say, "Of course, that was when John - with his usual impeccable timing - said he didn't approve of mixed marriage."
In addition, actors - especially comic actors - often claim that the key element in their performance is "Getting the timing right."
