One of our teams has pre-bowled a couple times. This was a few years back. I remember asking our secretary (or someone), if someone shot a 300, did it still count (as an honor score) and was told it would.
However the current rule says it does not. Is this something that was changed recently, or was it always this way? Also, what is the logic behind not allowing it?
From USBC Rules:
111e/7 Can you explain when High Scores will or will not be recognized by USBC?
USBC will recognize High Scores bowled when:
1. Two scheduled opponents pre-bowl or post-bowl together. (Direct Opposition.)
2. The entire league is rescheduled.
3. A team is bowling alone during league play because the opposing team has pre- or post-
bowled.
4. A team bowling alone because the league has uneven number of teams.
High Scores will not be recognized by USBC when:
1. An individual or team bowls unopposed.
2. Games are bowled unopposed before or after a league session.
3. League has uneven number of teams and the team without an opponent does not bowl
with the league.
4. Two teams from the same league that are not scheduled against each other bowl together.
5. Two teams from different leagues bowl together.
