Lack of consistency seems entirely normal to me for a blog post.

At a certain point the information is simply redundant. The meaning of the naked number can and will easily be inferred from context. You don’t even notice it. Both while writing and also while reading. A proper proof reading will catch that (maybe, though I myself am actually hilariously bad at proof reading and miss obvious stuff all the time, so being able to properly proof read and catch things always seemed like a super power to me) but I don’t think this blog author does that (and I don’t really expect it? It’s fine …)

It totally get that there are people who will be endlessly annoyed by that – I’m also annoyed by people using quotation marks the wrong way. But it doesn’t really impact readability of the context is clear enough (as it obviously is in this case).
