Bill, slow down. Stop. Think. Don’t post.
Online doesn’t require scorekeeping. Ergo, there is no need for someone to use a gimmicky time control to avoid scorekeeping requirements. That was the point I was making.
Do the rules explicitly state that scorekeeping isn’t required in online chess, Tom, or are you just assuming that MANUAL scorekeeping isn’t required because the online system keeps score?
Are there online chess platforms that don’t keep score?
This is why I suggested upthread that the online rules should specify that the online platform must keep score to be certified for use in US Chess rated events.
Well, as it turns out, and as was pointed out in the latest episode of “The TD Show”, manual scorekeeping is completely useless in online chess according to the new rules in effect today. The new rules explicitly state that a manual scoresheet may not be used to support any claim whatsoever:
Okay, okay, you’re right. 
My main point, though, is that IMHO controls like G/5 d/25 should not be ratable at all. Not OTB, not online. Not regular, not quick, not blitz. G/5 is too fast to be anything but blitz, and mm+ss>=30 is too slow to be anything but regular. So the combination should not be allowed.

Yes, that is Mr. Doan’s point.

Bill, I don’t think the rules currently exempt either quick or blitz OTB chess from scorekeeping.
I’m sure they do in practice, at least. It used to be explicit in the rulebook, but somehow it has disappeared from the 7th (and possibly 6th) editions. This important omission badly needs to be fixed. I’m confident that virtually nobody who has ever run a quick or blitz OTB tournament has ever required scorekeeping.

Technically it is not part of the rules but it is in the rulebook.
5C
TD TIP: Here is how the changes referred to in 5C will be implemented and administered:
Quick Chess: A Quick Chess event is for a person who wishes to play many games in one day and not have the
results affect his regular rating. The time controls in a Quick Chess tournament are designed to be a single time
control of more than 10 to less than 30 total playing minutes per player, one second delay or increment counting as 1 minute playing time. 10 < mm + ss < 30. Sudden-death rules are used in Quick Chess events, except scorekeeping is not required.
But not OTB blitz chess, and TD tips (as Tim keeps reminding us) aren’t the rules of chess.
So, the fact that scorekeeping is not required, in both quick and blitz, has been demoted from a rule (in the 5th edition or thereabouts) to a TD Tip.
This suggests that the rulebook editor, noticing (or having it called to his attention) that the rule had disappeared, quickly added it as a TD Tip, since adding it as a rule would have required Delegate approval at the next annual meeting.
Well, I’m glad it’s least a TD Tip. Better there than nowhere.
