Another thing to keep in mind in relation to meeting the LSA performance criteria is who, besides you, is going to know for sure what the stall speed (or any other parameter) really is. If you say the stall speed is 51 mph, as long as that's plausible who's going to even give it a second thought? The regulator's certainly not going to get in the plane and verify it.
I'm not suggesting you falsify your test data or anythig like that, but aviation is full of optimistic numbers, and the difference between 51 mph and 55 mph could well be within the margin of error of your instruments in any case. ASIs tend to get inaccurate at low speed and high AoA.
