Hello  
I have a problem calculating blended to find out the % of visitors to a feature.

As you can see on my screen i have 2 differents rate.

If I made the calculation on excel the result is 53.93% but i would like to have a time serie chart and to made this i need to add the dimensions DATE.

But if i add this dimension the result change to 67.12%

first rate
