according to the definition: (number of concordant comparisons - number of discordant comparisons) / (number of concordant comparisons + number of discordant comparisons)

the limit for best score should be 1 (number of discordant comparisons = 0)

Following the logic of this formula I guess you are right. Maybe @larskotthoff knows something more. Probably a copy & paste error of the G1 index?

Yep, that's a typo. I'll fix this.
