When will the meeting be? Which line shows productivity correctly?

Man: Sarah, can you fix a date for us to discuss the new advertising campaign with Nick Bradshaw? It’ll have to be next week. I can manage the twelfth, fourteenth or fifteenth, as long as it’s after three-thirty.
Woman: Right, but Nick said he’d be away until the fourteenth, so it’ll have to be the following day.
Man: That’ll be fine.

Man: These figures are interesting, aren’t they? I expected to see the highest productivity in the earliest part of the day, and the lowest at the end.
Woman: But... in fact, the peak time’s just before midday, isn’t it?
Man: And performance is better at the end of the day than it is after lunch. I imagined it’d be the other way round.
