People have asked if some of the numbering has been missed out on the new DQ sheet that you can now down load off of British Swimming Website.
The answer is no
The number relates to the FINA rule so for example the glaring example is that it looks like they have omitted rule 6.2 however, 6.2 rule under FINA states
Backstroke
SW 6.2 When a backstroke ledge is being used, each inspector at the starting end shall install and remove the ledge after the start.
Which as you can see you cannot be disqualified for hence not mentioned on the DQ sheet.
