Still missing the point/s, CTD

I haven't listed all the 'benefits' of including all genetic changes under the term 'mutation', but everyone should get the picture, and that's all the time I'm allotting for the purpose just now.
That was a tad amusing. But there's no real mystery. I only hope I didn't strain anyone's patience by taking so many words to explain something so dreadfully obvious.
Yes, amusing, indeed, however the message was clear: if the DNA is changed then it is called a mutation. What you do with the information is your matter.

I'm much more concerned that they start & stop exactly where they're designed to start & stop. If they don't, bad things will happen.
Sure it's cut & dried. Mutations are random mistakes. Recombination is a design feature. (A marvelous one, to be sure!) Doesn't get much simpler than that.
Except that this design feature causes bad things to happen when it doesn't start and stop at the right points, eh?

Let's use a little analogy. We have two decks of cards, each sorted exactly the same way (assume ace to king, spades, hearts, diamonds and clubs for instance). We cut each deck at exactly the same spot and trade top portions. No matter how many times you do this, no matter where you cut the decks, the order of the cards will still be the same. If the decks are identical, then you can't tell that anything "marvelous" has happened.

So how can you effect a difference on these decks of cards? One way will be to have one deck change before hand, say by adding a card or deleting a card. The problem here is that, again, as long as you start at the same point, that you will only be moving this change from one deck to another, while the others remain the same. Still nothing "marvelous" to wonder at eh?

What you need are multiple changes, as then you can mix one change with another by this process to get a double or multiple change. The problem here is that if "Recombination is a design feature" that it depends entirely on the existence of differences in the DNA, on changes to the DNA, on mutations, and therefore mutations are also a (marvelous) design feature (they just seem random to those who don't know how marvelous a design feature they are).

The other way you can effect similar change is to have the cut of the cards happen at slightly different locations, say leaving a 9spades in one deck and moving the 9spades from the other deck with it. The astute observer will note that this is the same as a precut change to duplicate a 9spades in one deck and delete a 9spades in another. As with other changes above, you need to have multiple changes to be able to accomplish anything "marvelous" by this process. In other words changes caused by point shifts in recombination are the same as changes caused by point additions or deletions. The end result is the same: recombination depends on the pre-existence of multiple changes in the DNA and thus if "Recombination is a design feature" then it depends entirely on the existence of differences in the DNA, on changes to the DNA, on mutations, and therefore mutations are also a (marvelous) design feature (they just seem random to those who don't know how marvelous a design feature they are).

One may just as well say that evolution is a "marvelous design feature" and be done with it. Now what you decide to call "marvelous" (or "magic") is up to you, and everyone is entitled to their own belief on that matter, and if you (mistakenly) conflate one "marvelous" feature with a (good) part of the design process, and another feature with a (bad) part of the design process, the only one you affect with your misunderstanding is yourself. Curiously such beliefs have no effect on nature and the way things behave, and certainly no effect on evolution.

Enjoy.
