This method is called the ratio of the sum, which is the app's default behavior. For example, if there are 2 issues i.e., issue1 has an SP value of 15 and issue2 has an SP value of 45, then the calculation according to the Ratio of the sum method would be
15/60 + 45/60. The result would be 1.  Also, there is another way of calculating Sum of ratios. How does it work? Alright, the calculation will be performed as (15+45/60+60) i.e., wrapping the above expression with MULTIPLY function. The end result would be 0.5.
