There have been several threads about this same thing happening, weight being off 4,5 or 6 grams, thats ridiculous, and the funny thing I hear some people say is " well how do you expect a company with only 20 employees to weigh each disc accurately, I mean thats not an easy thing to do?". My answer is " put them on a cheap digital scale and do it?" doesn't innova, discraft and other major companies make millions of dollars? Cant they buy a 50 dollar digital scale? It does seem retarded and you probably wont be able to ever justify to me how it happens and why, theres no reason for discs to be off on weight. If innova wants to pay me 15$ an hour ill sit there at the factory and weigh their discs for them since it seems that they cant do it themselves correctly. I dont get how hard it is to weigh a piece of plastic to within 1 gram. Step #1, put disc on scale. Step#2 write the accurate weight on bottom of weighed disc. Is that rocket science, I guess so because they cant do it.
