I think you're getting too nitpicky. Categories are for convenient sorting. We don't need to break them down so minutely that each one only has two examples. Just pick the closest one that fits.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"It can be a problem. There can be a lot of space between galaxy clusters. Same goes for galaxy superclusters.
So there should be at least two new categories between X-3 and X-4.

"If there are any gods whose chief concern is man, they can't be very important gods." - Arthur C. ClarkeDid you read what I said? We're dealing in narrative conventions. Astronomy is not the point.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"No, not really. I agree the division at this point is pretty pedantic.
When you move beyond blowing up a solar system, the scale matters less, really. Is blowing up half a galaxy really that much different from a narrative position than blowing up the entire galaxy?
Don't take life too seriously. It's only a temporary situation.The real problem with that scale, as I see it, is that the distinction between a Scale 5 and a Scale 6 is completely arbitrary, as far as it can only meaningfully be conveyed by the distinction of having a character or narrator say whether they did manage to kill off single-celled life or not. Unless you're going to let your story span a few billion years, whether life develops again is a footnote.
And a single uttered line on the fine details of single-cellular life is hardly worthy of a class of Apocalypse on its own.
Class X-3 makes sense. To an audience, their monkeysphere cannot really even begin to comprehend the distinction between a galaxy-arm, a galaxy or a supercluster. They're all just the space between "our solar system (Sun out to Pluto; the Kupier Belt does not exist in Our Common Understanding of the Solar System. Nor does the Oort Cloud, but that one might not actually exist...)" and "the entire universe". Distinguishing between a galaxy, a cluster and a supercluster makes no more sense than distinguishing between "the Inner and Outer System", "everything within the Kupier Belt" and "everything within the Oort Cloud."

I was looking at the Apocalypse How scale, and there's something about it that bugs me. Namely, the discrepancy in scale between X-2 and X-3, and the discrepancy in scale between X-3 and X-4.
A star is a lot smaller compared to a galaxy than a planet is to a solar system. I propose several additions be placed between X-2 and X-3, tentatively titled X-2.25, X-2.5 and X-2.75. X-2.25 would cover something on the scale of the destruction of small portion of a galaxy (Say, a quarter or less), making it the galaxy-scaled equivalent of a type 0. X-2.5 would be a destruction of between a quarter and half of galaxy, making it the galaxy-scaled equivalent of a type 1. And X-2.75 would cover the destruction of a large portion of galaxy.
There should also be two categories between X-3 and X-5 (Covering the destruction of a galaxy cluster and a galaxy super cluster respectively.).
Feedback?
