Good points. One more:

* Getting interrupted partway through the edits. I call this the "working out of your home office when you have kids" error.

Now, I don't copy-paste-edit similar lines anymore. I find that editing is often slower than typing the line from scratch.

I think that's a function of text editor or workflow often.

A vim user that makes heavy use of recording and/or search-replace will be able to do large copy-paste-edits very quickly.

In fact, I think this might be another potential source of error. Depending on how the recording is done, or how an edit is scripted, it's very likely that the first and last lines are the two special cases. The first line, however, will be given the most scrutiny. This leaves another potential source of "last-line" errors; the use of editor features that make such a line the exception.

I'm interrupted by my boss far, far more often than I'm interrupted by my kid. A dozen times a day isn't unusual.
