What the data shows

- Close agreement: Jev ranks the requests at 0.74 with the raters, a higher agreement than one rater has with the other four (0.52), though that yardstick isn't strictly fair (see Caveats).
- Same center, wider spread: Jev averages 2.23 on the 0-4 scale, the raters 2.26. Jev's ratings spread a little more (0.82 vs 0.74), so it hears slightly stronger politeness and rudeness.
- Politer than people heard: "Having said that, I don't want to drive anyone away just because they can't write well. The question is, where do you begin?" sounds warm to Jev; the raters gave it 9.6 out of 25. "Thanks for starting my page for me, that was very sweet of you. ^_^" is very polite to Jev and middling (13.0) to them.
- Ruder than people heard: "Thanks for the help! That info should be on [a link] in easy to read form, no?" got 19.4 out of 25 from the raters and is only neutral to Jev. "Will you accept that by renominating the article last night you were essentially discarding Delldot's and my previous review...?" also reads far ruder to Jev than to the raters, who rated it 17.8.
What it means, and what it doesn't
Jev has a good ear for tone, about as good as the average of a small panel of people. In the requests where it differs most, it takes warm words ("sweet of you") at face value, and it is less charmed than the raters by a thank-you that ends in a tacked-on "no?".
It doesn't mean Jev hears tone the same way in every setting. Wikipedia talk pages are a narrow slice of writing, and Jev read each request without the conversation around it.
