Thanks for trying out. yes you are right. Tips are not upto the mark. Our algo tries to put a site in 8 buckets -b,..+A and provides tips. So it's not that accurate when evaluating 50% versus 53% but mostly accurate with difference of over 10%.. so 50% won't be same as 60% for example.. of course it is based on limited amount of data we had to guess it..point taken.. we really appreciate your feedback and will incorporate.. cool.
