Advantages of 2 circuit dominator carbs for drag racing?

All I know for sure is my 1050 Pro Systems gas and my Mark Whitener modified 1250 gas both run better with 2 circuit than 3 circuit with the same BLP wide body metering blocks (that can run 2 or 3 circuit) in the 1/8 mile and 1/4 mile.

Guess because of the title of this thread, no one else is likely to join in.

Braswell is the one that made more than 3 circuits popular in Pro Stock.

I think 3 circuits in stock Holley dominators was popularized as a sales gimmick after the real need was only for tunnel ram or individual runner Pro Stock briefly. The real benefit was the use of annular discharge boosters, with the 3rd circuit coming along for the ride to be an "improvement" to make more sales. After that Holley never really developed any good 2 circuit dominators.

When running the wide body 3 circuit block as a 2 circuit the idle bleed goes back to the outside? and you just plug all the inter. feeds?
