I've configured JLex Review with 3 rating factors, However, when I do a test review and set these 3 factors to exactly 9, 10, 10 (out of 10.0) respectively, I then get an summary rating of  4.0/5 and only 4 of the 5 stars are hi-lighted.  
I am wanting a more accurate numerical rating since the ratings I used total 29 of 30, which  = 96.677%, so equivalently = 4.833/5 . So the presented summary of 4.0/5 is not correct if rounding to a single decimal digit.. desired is 4.8/5.  Also when rounding to integer number of stars, I'd expect to see all 5 high-lighted.

Any idea how to correct this.

Cheers, Larry
