For time difficulty I was thinking more like:
1 star = 1-15 hours
2 star = 15-30 hours
3 star = 30-50 hours
4 star = 50-100 hours
5 star = 100+ hours
Then factor the time rating along with the skill difficulty rating to get the overall score.
Of course White Knight Chronicles 600-1000+ hours should be an automatic 5 star in my time example. Thats like factoring in 6-10 more 5 star time ratings. Would come out to a 4.6 overall rating for 1000 hours of time and if the skill difficulty was rated a 1.
