With 'gap' I mean that (to me) there does not seem to be a big difference between latest models if you average out their performance across the conditions spectrum. But the advantage of latest models seem to be concentrated in certain conditions (higher winds, rougher sea state, down wind especially).
I do prefer those boats which handle better and cartwheel less when it blows and waves are high and steep. Probably that means that in these conditions those models are easier to sail closer to their potential.
Other than that, I cannot really opine whether the groove range of the latest models are different than the older ones - I am not even sure whether that is actually a valid concept. Maybe the experts can chip in here.
