With all this depth measuring problems and unfair tag/lanyard/longer fingernails/linestretch etc advantage, wouldn't it make more sense to say that a new WR has to be at least 5 m deeper then the old one. Who says 1 meter is the holy number.
I never liked this 1 meter crap world records (no offence there of course for the total depth).
Like winning on points in boxing. Always disputes and problems with this. Go for a knockout. Nobody will dispute that.
Same for static . Not 1 second but minimum 10 seconds or so. Dynamic 5 meters sounds fine to me. Then you can also drop the rules about grabbing and touching the bottom , because you will never get 5 meters unfair advantage (if any) from that.

So unless we get nanometer precise electronic measuring equipment like in athletics or swimming with the electronic touch plates, lets make it simpler.
