Besides the one millisecond wait, there is also the time it takes to 
redraw the field and its contents every time through the loop. That adds 
overhead.

The "move" command is optimized animation, and is only one line:

   move field "foo" from 537,1 to 537,650 in one second

There's other variations you can use, take a look at "move" in the 
dictionary. You can move things using exact positions, or relative 
positions, in a certain amount of time, or at a certain speed.
