75% rule - what does it mean to St Julian's Bridge Club?
75% rule - what does it mean to St Julian's Bridge Club?

The EBU were to introduce a new constraint concerning the awarding of Master Points effective from 1st August 2015. Its introduction has been delayed until January 2016.

Here is a quote concerning the issue from their web site:

"Master Points would only be awarded for pairs events in which all the competitors are scheduled to play at least 75% of the boards used in the movement."

You might be interested to know how this might affect the sessions/competitions at St Julian's. The answer would be not at all. St Julian's is not affiliated to the EBU, so we do not award Master Points.
We don't use Master Points in our competition calculations but rather 'Wilsons' which are calculated using a similar method but have no such 75% rule.

The idea behind the 75% rule is a good one, the fewer boards shared between opponents, the more unfair the result becomes. However reaching a 75% share ratio would be quite difficult at St Julian's given the 2 1/2 hour time constraint we have on the room hire and a large field, meaning that the most boards we can play in a session is limited to 10 rounds worth, 20 boards. This table gives us the share ratio of the movements we use at St Julian's:
