As a % of overall damage, the boost from any given stat (including stats sharing the same class) is dependent only on how much of that stat you already have. At +200% character attack, each additional % of character attack will provide only 0.33% more damage--regardless of elemental attack or other stats.

While skepticism regarding difficult-to-verify statements about combo attack rates is warranted, "Attributed rates are inconsistent with the rest of the system" is not a great justification. I'm sure you've noticed by now that design simplicity, intuitiveness, and consistency are not this game's strong point. Not to mention random things like Gatcha rates haven't even been the same in the Nutaku version (compared to the DMM version at the same point in its lifetime). For all we know, the DMM wiki lists the correct rate for the DMM version, but not our version. Amidst this near-constant haze of confusion we live in, I choose to trust the best resource we have until proven otherwise.
