I had a physics teacher in college tell the whole class that if you're ever feeling like you did a problem right but the answer is off, just check for any combination of pi, 2, or 2pi and see if that fixes the problem.

For all that you've been saying that dividing by two isn't a huge deal when teaching kids, is multiplying by 2 really such a huge deal that we should overturn an entire industry convention and force people to rewrite new computer programs and algorithms because they're not supposed to draw on pi anymore?.
