Ratings with stars in Ubuntu Software Manager display incorect score

[spiral]

Binary package hint: software-center

This is the example I found that reflects the problem:
Guake Terminal has 10 ratings, 9 of them are with 5 stars, and one of them is with 4 stars, an average of 4.9, but instead showing 5 stars as an average score, it shows 4 and a half. There is a screenshot included to prove it.
My suggestion would be that for the remainder if average is under .33 that it is rounded to 0 for stars, if it is between .33 and .66, to half of a star, and above .66, rounded to 1 whole star.

On Precise Software center displays partial ratings too, not only thirds, but even smaller fractions of stars, so I think this can be set as fixed.
