Do wind and hand timing change the points?

• One timing system: "Only one system of timing may be applied throughout each individual event."
• What that means: the commentary's example is a photo finish that fails for some heats of an event. Hand times and automatic times cannot be compared directly, so every athlete in that event is then scored on a hand time, using the table for hand times.
• Event by event: if the other events all have photo-finish times, the electronic table is used for those.
• Hand timing: where there is no automatic timing, each athlete's time is taken by three timekeepers independently.
• Times for records: for a record, times from a fully automatic timing and photo finish system are used, whether or not such times are available for the other athletes in the event.
• Wind and points: the scoring rule sets no wind limit. The points stand.
• Wind and records: for a world record the Competition Rules require that, in the events where wind is measured, "the average velocity" must "not exceed plus 2 metres per second". The average is the sum of the readings divided by the number of those events. The conditions for each individual event must have been met as well.
• The time limit: a competition spread over longer than the rule allows cannot produce a record total.

A mark made with too much wind behind it is called wind-assisted.

Hand times are quicker than automatic ones for the same run, so mixing them inside one event would hand some athletes points they had not earned. Wind is averaged for records because a combined event has several measured events, and a strong wind in one can be balanced by still air in the others.
