Appendix A: 
German proposal to change the categorization for tournaments on the European Go Rating List

The current categorisation reads as follows.

'* class A - well organized tournament of at least Grand Prix standard,
  recognized by EGF time limit requirements: adjusted time minimum 75 minutes,
  basic time minimum 60 minutes weight for inclusion to EGF ratings: 1.00
* class B - well organized tournament recognized by EGF member
  time limit requirements: adjusted time minimum 50 minutes, basic time
  minimum 40 minutes weight for inclusion to EGF ratings: 0.75 
* class C - casual or club tournament recognized by EGF member time limit
  requirements: adjusted time minimum 30 minutes, basic time minimum 25
  minutes weight for inclusion to EGF ratings: 0.50 

Remarks:
  * Adjusted time (TA) is calculated as [...]
  * The GP standard required for A class events is defined in related documents
    of EGF Rules and Ratings Committee which are available at the EGF
    site. Specifically, the tournament should consist of at least 5 rounds,
    have sufficiently long time limits, no handicaps in the top group, and
    good playing conditions and material.'

Proposal:
Change categorisation for class A tournaments as follows and omit the remark
on GP standards:

'* class A - well organised tournament recognised by EGF member; time limit
  requirements: adjusted time minimum 75 minutes, basic time minimum 60
  minutes weight for inclusion to EGF ratings: 1.00'

Reasoning:

From our point it is not clear why a five round tournament is (usually)
considered as category A, whereas a three round tournament of the same standard
is (usually) considered class B. In particular, the three games of players
leaving after the first day of five round tournament are considered more
important than if there would not have been a second day.

Additionally, single championship games (as in Britain) or three round
preliminaries (as in the Hessian championship) do not classify for class A,
although the games are more important to the players and usually even have
at least as much thinking time than most GP tournaments.

To avoid this ambiguity, the categorisation should only be based on thinking
time limits (beside the recognition of the member country).
