Let's pretend we have 5 people in an age group. These people are A, B, C, D and E. A is the fastest, B the second fastest etc. All but C opt in to allow there age and times to be displayed.
If you were to look at the age group results, you would see something like this. Not that C's result is missing, but still accounted for.

1. A single 9.23 average 11.58 |

2. B single 10.35 average 12.17 |
4. D single 18.83 average 20.67 |

5. E single 20.62 average 24.60 |

that still leaves the issue of what constitutes a minor as you said in you post, but if we can, then I see no reason why my way couldn't work.
