Even that the windrange has increased and the kite has improved, a 8 is still a 8
You mean like a 2011 12m is still a 12
Except it had a similar range to the 10m. Thats why I asked for the 'relative' wind range of different years. Changing foil shape changes wind range. You need to fly an old TD 2 14m in 20k, then tell me all 14m are the same. A Rally 12m does not have the same range as a 12m RPM.
