In the rulebook
5B2. The organizer is to indicate the time control, including the delay or increment, in all advance publicity as minutes (mm) and seconds (ss). For example, G/90 inc/30 (or +30); G/30 d/5; G/10 d/3; G/5 d/0.
This wording was considered a bit confusing. It can be read as either requiring the time control in all advance publicity, or it can be read as requiring any advance publicity that happens to have the time control to have it in minutes and seconds with delay and/or increment specified. I thought that the original intent of this rule was to change time controls like 40/2, SD/1 (when the 2 or 1 are hours even though some would wonder if they were minutes) to instead be listed as 40/120;d5, SD/60
Passed by the delegates
5B2. In all advance publicity which specifies the time control, the organizer is
to indicate the full time control, including the delay or increment, as minutes
(mm) and seconds (ss), e.g. G/90 inc/30 (or +30); G/30 d5; G/10 d3; G/5 d0.
The time control must be specified in Tournament Life Announcements and
should be specified in other publicity such as flyer mailings, email and on web
sites. It is acceptable for abbreviated publicity to refer the reader to more
complete tournament details posted elsewhere.
