RSGB Contest Special Rules 2015

S5.
Scores will be normalised for each band/session as follows.
Score for each band/session = (Score achieved x 1000) divided by (Band/session leader score).
For cumulative contests the overall score will normally be calculated from the best 3 normalised session scores
It is impossible for you to determine your best sessions without knowing everyone else's scores, so please submit your logs and scores from all sessions in which you were active and allow the adjudicator to calculate your best sessions.

Stations may move location between individual cumulative activity periods
