Lumpy Lycra: yes, gold times were based on W21L when the BOF lists were published.
does this not ask the question: why cant you apply the old award calculationsto (and those STLL used for JWM 1-4) to each individual JMW5 course?! or have i missed the point?
Yes, you have a bit. The idea was to produce one gold standard for each of JM5 and JW5, not separate S, L and M badges, which is what your idea would produce. After all, they are meant to be at the same technical standard. Also, it was designed to produce a more consistent award - junior numbers are just too erratic. We experimented with basing on junior times, and it just didn't work.
.I agree with this it would be pointless to have JM/JW classes at the national events as there is always enough people to run each class and I don't think encouraging newcomers should be a concern at national standard.
The idea behind JM/JW classes is not about encouraging 'newcomers': that's what district and local events are about. Indeed, take a look at regional events, there are very few newcomers at them. They are about providing a sensible progression, particularly for young people who don't conform to preset steretyping of what somebody of a particular age should be doing.
It depends what you mean by 'enough people to run each class'. Just a random snapshot: at the 0007 National Event (one of the bigger ones this year), 16 of the 27 junior age classes had less than 10 competitors, most of those with less than 5. Not exactly great competition, which is surely what National Events are about. And 27 different age classes!! Would be fine if we had hundreds doing them, but we don't, and the quality of competition suffers.
