I'll just take a moment out of my busy day to point out exactly how stupid it is to worry about some made up protocol regarding measuring drops. If you are so desperate for bragging rights but want to be honest about it. Just eyeball the drop, give it a good guess, and tell people what you think it is. If they try to hate, tell them you don't care if you truely know the exact height of the drop and that you are just relating an estimation and the numerical value is not a big deal to you (this should be true if you ever grew a brain). If you know how tall you are then you can get a good enough idea of the actual height to properly describe it. Measurement nitpicking is for idiots who think they will gain respect from people via their achievement claims and the clowns who think that it is somehow crucial to the balance of forces in the universe to hate on every pimply teenager who thinks his 2 meter drop is 4 meters. My drop (dick) is bigger than your drop (dick). It should go without saying that the height of a drop is not the only factor in what makes it difficult or hairy. Which still is taking away from the real point. You should only worry about the relative size of a drop, relative to you (as goes for everything in this sport). Is that drop bigger than what I'm comfortable with? Is it cleary farther than my current skill level seems to permit? Is it big compared to this other drop I do? If the only reason you hit drops is to validate yourself in the eyes of your friends/girls/strangers then maybe you don't enjoy them enough. Please folks, just ride, have fun. And if you must give a numerical figure for any measurement of distance for drops/jumps/gaps make an honest guess and reduce it my 30%. At least that way you avoid the hating, and when someone sees you clean it in real life, they'll be pleasantly surprised. Plus your modest estimate will help keep others humble when they feel like big boys for hitting the same drops.
