Massed Start Group Age Standards

Velociraptor Individual Group Ride Age Standards for Massed Start (or ability pursuit, i.e. non-age based Australian Pursuit). Regular Length (i.e. 64 k)
We might like to try the massed start format occasionally (instead of 5 small ten year age groups). Also, we may wish to try an Australian pursuit based on ability not age (e.g. 3 or 4 groups starting at 2 or 3 minute intervals, slowest group off first). In these cases the following comprehensive age chart could be used.
Large gaps between 10 year age groups are eliminated since this format does not embody age group start gaps. Yearly increments are slightly diminished to offset the benefit of increased drafting.

77. 1-59-22
78. 1-59-53
79. 2-00-24
Increments 79-89: 41 seconds. Thus, standard for 80 is 2-01-05, etc.

This massed start age standard chart could easily be adapted for events of shorter (hill climbs) or longer duration (72+ k road races).
Note that under BCMCA rules (given standard 10 year starting gaps) in group riding a woman is classed with a male 15 years her senior. But in time trials she is classed with a male 8 years her senior.
If this massed start age standard chart seems unduly hard on 70s + we could build in bonus start gaps between the decades, e.g. 39-40 20seconds; 49-50 30seconds; 59-60 40 seconds; 69-70 1 minute; 79-80 1 and ½ minutes.
