Narrative:

Training in progress on freeway sector. We had discussed the new change coming in the 7110.65 chapter 5 regarding opposing base legs and ways to mitigate the issue earlier in the session. My trainee had aircraft Y on a base leg of 170 degrees and 4;000 feet and had just cleared for the va via a 230 heading (all in compliance with directives) to runway 26. The opposing final had aircraft X northbound at 4;000 feet; airport in sight and planned to turn to final but got distracted by coordination with the arc about a light aircraft inbound from the southeast. Visual separation was applied by both my trainee (the aircraft Y) and the opposite final. Aircraft X was cleared for the va runway 25L; but overshot their final. Ensure offset base leg headings (I instructed my cpc-it to listen for the other finals base headings); i.e. 180/010. Make it a point of emphasis to have the finals talk to each other more until these new .65 procedures settle in. It will be a slight learning curve; but my cpc-it seems to grasp the concept and we will consider this a high priority for the next sessions.
