At high OPL, can players use score dials in addition to tracking score in writing?

Ruling: At high OPL, players can use score dials as a visual aid in addition to the required written score tracking, though the dials don't officially count.

Nuances:

• At low OPL, electronic devices or dials can be used to track score without written tracking
• At high OPL, written score tracking is mandatory, but additional visual aids like dials are permitted alongside it
• Both players must be writing down scores for this to work properly
