- Success rate
- 100%
Active missions are excluded from the success rate: a live mission has no outcome yet, so counting it would report a rate the records do not support. 1 of the 3 records is still active, leaving 2 concluded. A partial success is a distinct recorded outcome, so it is not counted in the numerator, but it stays in the denominator.
