At various times there have been people who've asked about changing the rating system (the European Go Database [1]) to have their club games included. Actually, it's always been possible for you to do so, provided you follow a few rules.
The EGD description allows for a Class C event as follows:
Casual or club tournament recognized by EGF member Time limit requirements: adjusted time minimum 30 minutes, basic time minimum 25 minutes; (Fischer time: basic time 20 mins, adj. time for 120 moves: 30 mins - see remarks) Weight for inclusion to EGF ratings: 0.50 Adjusted time (TA) is calculated as TA = basic time + time equivalent to 45 (60) moves in standard (Canadian) byoyomi. Sudden death - implying adjusted time = basic time - is acceptable, provided all other criteria are met.
so all you need to do is ask for one of your internal events, say a Ladder or a one day tournament or a season championship, which uses clocks and has this minimum time limit, to be approved by our Ratings Officer [2] and then submit the results in the approved format. [If you use Godraw to manage the event then this will produce a suitable file.]
Easy, peasy...
I just hope Geoff doesn't get swamped by enquiries (sorry Geoff).
