I know! They should have a walkthough scanning thing like you go through at the airports - each pony could walk through it when being jogged! It could be shipped from show to show!
(just adding a bit of silliness - I’m guessing we’re at least 50 years from that being feasible)[/QUOTE]
Part of the question is, more seriously, what does it mean to be 14.2 hands? That sounds kind of like splitting hairs, I realize. A pony that is 14.1 hands is clearly going to measure as a pony no matter how or who you measure, if the pony has stopped growing and the first measurement was honest.
But, as you create ponies getting closer and closer to the limit, you start to see that small differences in how the pony stands, the length of the foot, the amount of hair on the pony, a slight error in levelness on the stick, all these things create some non-zero amount of error in the measurement that allow two honest careful measurements to vary by some amount. Even a truly leveled and calibrated laser doesn’t eliminate these issues.
And so this is how a pony that will measure under 14.2 EVERY time is a little different than a pony that will measure under 14.2 ONE time.
So, how much can it vary? How much are we willing to allow it to vary?
So that’s the engineering part of the problem, and that combined with deliberate fraud and the very high stakes (an eighth inch difference on the final card in some cases could be worth $100,000 (!) ) makes this a somewhat more difficult problem to Just Solve with say a computer scanner than it might otherwise be.
That said! (/nerdout) I do think the system we have would work fine if we just remeasured ponies at the major championships. It would just be part of the competition, as much as the model or the hack.
