With only 11hrs on type you ought to hand fly from TOD to touchdown so that you get a feel of the jet; practice to fine tune your skills to effect a smooth descent profile without jerking the airframe. It's what you have to do when the FMS goes on vacation; it's what you have to do when the controller takes you off the STAR [just as you've plugged in the very last detail of the entire anticipated profile] then gives you an immediate new heading, followed by more impromtu headings and altitude changes and speed reductions, . . . and changes your arrival runway all at once, then clears you for a visual on a runway where the ILS is out of service.
