You have good eyes. :-)
You are right, it should be placed at 36.33. I missed that.
Now, the reason why it is the capital is due to the large forest to the north. As this is a fantasy world (with elves, but not dwarves), the elves of that forest were mighty in the past, so there was a lot of trade to this capital. The elves are long gone, but tradition makes the seat of power remain on that place.
Anything else that you think it should change?
