As someone advancing in years these days, I think the new system is not too bad. I think the banding is a good idea, but should be more advisory with those in yellow/red advised to get a grip (for their own sake) and those in the blue attracting favourable comment in the all new 'physical stamina' box on the SJAR.
In summary, a better idea but a little too stringent rather than effective.
(And to all those people who ignored the 'don't go mad' on the maximal test last year, because the levels will go up next year...I told you so)
