Servo resolution: 180 vs 256

I looked at the servo sweep example and it looks like the servo object has a range of 0 to 180. While this seems like a handy method of specifying angles, doesn't it sacrifice about 75 values of resolution because you could be specifying in 0 to 255?

For finer resolution use microseconds.

I am an idiot, I should have looked at the documentation before opening my mouth. Thanks
