This seems reasonable, and though the status doesn't mention it, it seems like there's a lot of coverage reduction in the result. I guess that's expected since we didn't really test a lot of the error branches?

The reduction is expected as earlier an if-clause was considered covered even if only one of the paths was covered. Now it is only partially covered (not sure how that counts as percentage though). With that said, I do not really understand how some things that are not conditional are considered "partially" covered now.
