I would to ask all mentors/teachers to continue having your teams to include engineering logs as part of their routine practices, no matter whether they will be scored at the competition or not.
HERE is a guideline I wrote up for my students. You may find others like this one from Robotics Education & Competition Foundation) . . Our job is to cultivate this crucial skill in pre-college students. The approach in my guideline aims to strengthen the habit while ensuring the log remains efficient and informative, but not become needless chore.
Hope this helps.
