That's a horrible idea. I cannot understand why American cooks continue to insist on using volume measures for things that are CLEARLY better done by weight, when really quite affordable and very accurate (well, very accurate for the home baker, perhaps not so much if you're a diamond merchant) digital scales are so readily available.
In addition to the problems of how much flour is actually in that cup of flour, the fact is that measuring cups (except for Pyrex glassware) vary by around 10%, plus or minus, from what an actual cup-by-volume is supposed to be. That's 10% less to 10% more (roughly) for a quite wide 20% range.
Don't do it! I'm in the process of converting all my cake recipes to weight measures, or finding a version that already uses weight measures. Frankly I have neither the time nor the inclination to muck about with baking recipes that can vary wildly depending on who originally measured out some flour and decided that was "one cup". That "one cup" could vary anywhere from as little as 3.5 oz to as much as 6 oz. What a mess!
