A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Where it wins and where it pays
Every boat is judged against its own measurements — length, weight, sail area. The quicker those say it should be, the more it has to deliver just to break even. Going fast is not enough: it has to go faster than its own numbers promised.
Soft conditions suit it. In the light it does more than its numbers promise, and gives some of that back when the wind arrives.
Where it gains
Its best ground is on the beam in light air, where it outruns what it looks like on paper, and by a margin worth having. It holds that advantage to windward as well, so the gain is not down to one leg of the course.
Where it pays
It falls short cracked off once it pipes up, giving away time it never gets back. That is weight that has to be driven rather than released.
Above the line it delivers more than promised and gains on the fleet. Below, it falls short. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
Full width is 0.6 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.
