We've integrated UGC into our 2011 SP1 HR1 implementation and I've noticed something odd.
A single user has rated a component 5 - but in the GUI only 4 stars are shown!
I've checked the db and there is only one rating of 5 so the Average Rating is correct - but only 4 stars - thats a bug right?
UPDATE
In addition, when we view ratings through the Control Room I can see information like:
Average Rating: 5
Individual Ratings: 1
neil gave a rating of 4.166667
There seems to be a logic bug here - one rating of 5 != 4.166667!
