Just remember thats where it's trying to be and 98% of the time it should be there.

Please note that the only thing Matt is pointing out are possible error conditions which should not be encountered in normal operation.
1) Do not command your servo to go into a position where the servo's movement is physically limited.
2) Setting the pwm value is where the servo will end up. This is pretty accurate. If you are worried about the speed in which the servo gets to the commanded position versus the speed of your processing loop then use the Hitec specification for the speed of your servo to figure out if you need a delay.
