A control circuit configured as a multi-standard optimizer generates a radiotherapy treatment plan. The circuitry then determines a resultant dose distribution according to the radiotherapy treatment plan, and displays at least a portion of the resultant dose distribution on a display. For example, the latter may include presenting at least one isodose line on a display. The control circuit then detects a user manipulation of the user interface. By one approach, this manipulation does not include a corresponding immediate movement of any portion of the presented resultant dose distribution itself. In particular, the detected user manipulation does not cause a drag movement of the isodose line on the display. Upon detection of a user manipulation, the control circuit modifies the dose value at a particular location on the presented final dose distribution in accordance with the user manipulation of the user interface to provide a modified dose distribution, and/or a new candidate radiation therapy treatment pl
