I know that G/25;d5 qualifies as Regular rating, but does G/25;+5 also qualify?
As long as MM+SS is 30 or more, the event qualifies for regular ratings; G/25;d5 and G/25;+5 both meet that condition.
For OTB events, if MM+SS is between 30 and 65, the event will be dual-rated under both regular and quick.

If G/25;d5 is regular rated, why wouldn’t G/25;inc5 be regular rated? G/25;inc5 will always give the players at least the same amount of overall time for the game than G/25;d5, and G/25;inc5 will give the players more time for the game overall than G/25;d5 if at least one move is made in less than five seconds.
Jerry,
Rule 5C notes that “For the purposes of rating G/minutes and inc/seconds (or d/seconds), add minutes (mm) and seconds (ss) for total playing time for each player. That is, total time equals minutes plus (seconds times 60) or mm+ss; e.g., G/60 d/5 = 60+5 = 65 minutes total playing time for each player.”
…that is to say, delay and increment are interchangeable for determining if a game is Blitz, Quick, Dual, or Regular.
About the set time limit. It’s set to see if you play all three Reg, Quick & Blitz against an opponent & playing the clock as an opponent. The clock would be Blitz while Regular & Quick would be against an opponet.
I’m not sure whether this is the correct forum for a question, but I recently observed a G30+0 sec increment “dual rated” (regular and Quick) quad event in Richmond, CA where the tournament director told participants in the rated section that writing the moves on the scoresheet was not required. I was aware that writing moves on the scoresheet was not required if one of the players has less than 5 minutes remaining on the clock, so called “time pressure in sudden death,” but I was surprised that the “regular” rating part of “dual rated” game can be played without players being required to write the moves on a scoresheet when they have more than 5 minutes on their clocks. My understanding is that “Quickplay” rated games can be played without a score sheet, but if “dual” rated, the “regular” rating requires that players record their moves on a scoresheet. Because the games were sudden death in 30 minutes with no delay and no increment, not being required to write moves on the score sheet gave the players who wanted a scoresheet a significant time disadvantage, in my opinion. Did the T.D. make a mistake in allowing players not to record their moves?
This was incorrect. if mm+ss (main time minutes plus bonus or delay seconds) is 30 or more, then the tournament is regular-rated and scorekeeping is required. If mm+ss is 29 or less, scorekeeping is not required.
A dual-rated event is nothing more than a regular-rated event which also happens to be quick-rated, but that doesn’t change the fact that it is regular-rated, so scorekeeping is required.

I do not believe this is “incorrect” in all cases. If this event was also a FIDE-rated rapid event, then the FIDE Laws would be mandated where keeping score is not required. The use of the FIDE Laws is considered an acceptable variation for all US Chess-rated events.
There is no rule that states scorekeeping is not required is mm+ss is 29 or less.
Unfortunately that’s probably true, technically. It’s just one of those things that “everybody knows”. It probably slipped out of existence by mistake in about the 6th edition of the rulebook. It is a glaring omission that ought to be corrected.
For that matter, the same glaring omission might even apply to blitz, as well,

But there is at least a TD Tip!
