Medal times

Three of a map's four times are worked out from the fourth. Go forwards from the author time and the answer is exact; go backwards from the medals and it is an estimate, good to about a second.

Author time → the other medals

Exact
Gold
1:03:37.00
Silver
1:12:01.00
Bronze
1:30:02.00
Author
1:00:00.69

Gold is the author time × 1.06, silver × 1.2, bronze × 1.5, each rounded up to a whole second. The rounding up is the part people get wrong: 1:30:01.04 is published as 1:30:02, not 1:30:01.

Other medals → author time

Approximate
Author time, about32:45.00

Each medal gives its own estimate and they disagree slightly, because each was rounded up on its own; the average of the three is closer than any one. Good to about a second.

Do the four times agree?

Put in all four times from a map. The three medals are worked out from the author time, so on an untouched map they match exactly — if they do not, the times in that file were changed after it was built.

Start with the author time.
