Geeky question - does anyone know how the 'grade' is calculated?

It says it's a weighted average of the cards in the set, but damn if I can replicate it in Excel. I'm obviously missing something.

I am going assume your mean either Rating or Weight GPA in the set registry, not the grade of a specific card.
Weighted GPA - (based on cards you have only)
(Grade1*weight1)+(Grade2*weight2)...../SUM(Weight1+Weight2...)
Example....You have two 9s and one 10, missing 1 card. One 9 is weight 2, other is 1, the 10 is weight 1, the missing is 1 also.
(9*1)+(9*2)+(10*1) / 4
weight GPA is 9.25

Set Rating (top of equation is cards you have only, bottom is total set weight)
(Grade1*weight1)+(Grade2*weight2)...../TotalSetWeight
Same set as above
(9*1)+(9*2)+(10*1)+(0) / 5
Set rating is 7.4

Thanks for the formulas. I had figured out the rating, but not the set grade. I even tried what you posted, but must have made an error.

PM me your email address, I will send you my excel spreadsheet with the correct calculation in it.
