Be careful what you wish for, because you may get it.
I recall an FLL team that won an award, with consistency being one of the judges' high comments. The kids were greatly pleased to win an award, but one mentor was heard to say, away from the kids, "What, consistently mediocre?"
Granted, you want what you can do to be consistent, rather than haphazard. Doing one thing well consistently is better than doing 3 things inconsistently, only sometimes achieving the results you want. But I would say consistency is only one of the criteria needed to become a "great team".
