The difference of 540 points looks to be from a typo on #85 (Telenet): the reported score of 106 is equivalent to a level score of 43,560, but the claimed level score of 44,100 (which fits with the overall score) corresponds to a score of 160. I have adjusted the score to 160, as this looks to be obviously explained by a typo there.
