Adjusting simple (so it should be) shift register coding for a different result

Ah, but I am using a continuous rotation servo. Do my questions make a little more sense now?

I think the LEDs should reflect the servo, do you agree?

No, they do not. No, I do not.

Do you expect the LEDs to reflect the position of the servo? If so, which position, when? The servos are not commanded to go to a position, so reflecting the position makes no sense.

Therefore, you must mean that you want the LEDs to reflect the speed of the servo, but that doesn't make sense.
