I cringe when the word “accuracy” is introduced. The conversation tends to head towards simplistic measurements and goes off the rails.
For me, I need the gestalt right… conversations about accuracy tend to go to a few single measurements that completely miss the point. I have been a scientist and technologist for all of my life and when coming to carefully reasoned and logical conclusion based on all sorts of detailed data, I always ask my team, “does this pass the laugh test?”… if you look at the question… and the conclusion… does it make you break out laughing? As in, that is ridiculous! If so, go back to the drawing board, because there is something wrong with your premises. Ultimately science is about observation, then postulating possible causes and relationships, and if your theory doesn’t fit reality… it is wrong.
Anyway. Bring up accuracy, and typically over-simplified models of the world seem to get proposed and the whole conversation seems to go off the rails. So, I try to stay away from the word. I feel my system captures the gestalt of a musical performance… but I suspect measuring some simple parameters might say otherwise.
