Standardized zucchini

Us scientists often have problems with less than precise instructions and let's face it, recipes are often a prime source of loosey-goosey instructions.  So when a recipe asks for you to grate a medium-sized zucchini, just how much zucchini is that anyways?  Now TPP has often seen and occasionally raised zucchini the size of naval destroyers.  Now if that's a big zucchini, then how big is a medium?  No mass, no size measurements, no means of determining how much zucchini the recipe really calls for.  Medium?  This is quite annoying.  Now in my general judgment a zucchini  that is 9-10 inches long and probably about 2 inches in diameter at its thickest part is a medium-sized zucchini.  The navy calls to put in dibs on any that are larger.  Nobody should let zucchini get any bigger than 9-10 inches, but sometimes they can grow from 6-7 inches to 9-10 inches in a matter of 2 hours or less.  How a fruit so big can hide from view also remains an interesting question.  But it would help a great deal if recipe authors would attempt to quantify their amounts a bit more.  Is it too much to ask for some zucchini standardization out there?
