Roller Derby Referee Training - Jammer Lap Points - Ref-Ed.com

Ref-Ed.com - the online site for roller derby referee training. In February 2015 the WFTDA published a clarification on how to score jammer lap points correctly. For a lot of people this changed how they thought lap point should be scored and made it more complicated; myself among them. Since the clarification, I have found that is easier to describe how things are scored correctly with visual aids, hence this video. This video has been slightly updated; the jammers in the diagrams have been labeled "A" and "B" to help keep track of which jammer is doing what.
