The only one that had me stumped for a bit was 'undesirable' but even there it left only one possibility. The rest I didn't even notice, I read what you meant and now that you point them out I see them. Funny thing, the brain.

I have a rule when I write reports: don't send it on the same day. Let it sit for a day and then re-read it, from paper if possible. That's when I spot the typos and the weird sentences. If I proofread right away I just read what I think it should say rather than what it really says. Frustrating!
