I don't see anything obvious, so let's start with the basics.
- Double check your math. If you give us some model numbers and such for the servo and reduction system, we can do this as well. Also compare the peak current draw of the servo against the peak supply of the programmer.
- Check the batteries in the servo programmer. You never know.
- Run the servo with no load (not connected to the arm) using the servo programmer. Is the top speed about right? If you can check it easily (a load on an arm) is the top torque about right?
- Check the 10:1 gear reduction for binding or other inefficiencies. Can you operate it manually, and if so, does it go smoothly? The loss in a 10:1 gear box should only be 10-25% depending on type and quality (better for simple spurs or planetary, not so good for bevel gears or worm).

Sure, they can. But I'd bet you lunch they won't.
