Charlie gave a guide on the old forum of the number of meets it took to peak for events up to 400. If I remember correctly it was:
55: 4-5
100: 5-6
200: 6-7
400: 7-8
Is that correct?
No takers?
That sounds about right to me in the general sense. But I think it is more dependent on how good your base is to determine when you peak.
