I see... I'm not entirely sure that this isn't semantics. I had thought of "redundant" as a primary and a backup. Now, by backup, it needs to be able to back up the other one, not just a little bit, but 100%. Otherwise, it isn't really a backup, is it? So, call it "two primaries" if that's your preferred terminology; but the point is that I've suffered my whole life under the misapprehension that having "two primaries" (one to
back up the other) is referred to as
redundant. As in: NASA builds space shuttles with redundant systems, etc.
Now to take the extra step, to call it "dual redundant" must mean something. Either it's #1: "dual redundant" simply means "redundant" #2: as in BigV's example, it's
less than redundant (what if the pedal or master cylinder goes out?) or #3: "dual redundant" is a hyped-up marketing word, designed to fool the consumer into thinking that they're getting something
better than redundant (it's
dual redundant, IE twice as good) ... I may be wrong here, but I'm going with #3, "dual redundant" is marketing hype, "redundant" is the word they should have used.
