this is a very common issue with electronic parts. you can get the gyro sensors that many teams use from places like Digikey.
If you buy one they are $50. If you buy 10 they are $45 each. If you buy a thousand they are $20 each.
But its still pro-rated by the amount (number) you actually use. If they only come in a box of ten for $450, and you only use one, then you only used $45 worth the parts on your robot.

I don't see how you think this is correct. If the only way you can get them is to buy a box of 10 (ie: they don't sell them individually, then you have to account for the entire box of 10, even if you only use one.
This example is very clear:
Example: A team purchases a 4' x 4' sheet of aluminum, but only uses a piece 10” x 10” on their robot. The team identifies a source that sells aluminum sheet in 1’ x1’ pieces. The team may cost their part on the basis of a 1’ x 1’ piece, even though they cut the piece from a larger bulk purchase. They do not have to account for the entire 4’ x 4’ bulk purchase item.
I don't see any room for interpretation. If he uses one teaspon of his 10 kg drum, it doesn't matter. He can only get them in 10 kg drums, and therefore must account for an entire 1 kg drum.

That's not what it's saying at all. If it was, it would say so. It's saying that if I go out and buy a 4'x8' sheet of polycarbonate, and cut one part out of it that's 1'x1' and then use the rest for non FIRST stuff, as long as you can find someone who sells 1'x1' sheets of polycarb, you can put that as your cost, so that you do not end up "paying" for material you don't use.
