Just a point on Club Marks from a League Registration Secretary's point of view...
Every month I send a list of the club marks to the Referee Development Officer. He then looks at them; He is mainly interested in the Premier Division (Top division of five) marks, these have to be highlighted in red. Anything below Premier standard, although they are looked at, the main ones are the top games that you officiate on.
I can assure you that your club marks will not have too much of an affect on the games in which you are assigned to; For example, of the County Cup appointments here in Cornwall, only 2 of the top five referees (by mark) got a County final. The rest were the more experienced referees and academy referees. Even one of the lowest marked referees in the county got a league cup semi-final line.
Please don't get hung up on club marks! Only worry about them if your are consistently getting marked below 60 by each team that you officiate.
QB. I was also a referee appointment secretary. Instead of being asked to send club marks to the RDO to determine finals, we were instead asked to provide local area nominations for country finals. Whilst one would look briefly at club marks, so much more governs whether or not a referee would be nominated.
The biggest use of club marks are when local area referee committees receive below 50 mark reports / reports on referees, consistently for the same referee (consistently being the operative word). At this point, a mentoring / coaching scheme is initiated to support the referee - not castrate the referee.
