Disadvantages of using PSC?

Ok, so the parallax servo controller does have easier interface, where you set up servo movements frame by frame (at least thats why my understanding is, correct me if I'm wrong). But, let's say, you don't want the servo to move at a constant rate, but you don't want to calculate it's position at every frame. For example, if you wanted a servo's arm to move constantly for its horizontal travel (although arm swings in an arc, disregard vertical travel). Without a PSC, you could write a method that would incorporate trig functions to manage this(not too hard in java), but how would you do it with the PSC?

If you can do it witout a PSC, you can certainly do it with -- just send the position updates as required. The advantage of using the PSC, of course, is that it takes care of refreshing your servos so that you're not forced to send updates at a specific rate.
