DPReview how do you calculate the scores?
Nov 22, 2010

I am not sure if this is a known problem, I have never been on this forum before. Below are three examples of scoring in one of the recent challenges. I have taken the scores and the number of votes by hovering the cursor on the scoring bar chart and worked out the overall scores. Then I compared my calculated average with the average score awarded by dpreview. Example one is a 100% match, which is what I would expect. But Example 2 and 3 are significantly different resulting in these particular entries being some 10 or more places below what they should be. Not that I am bothered too much, just curious.

Example 1
2.5*1=2.5
3*2=6
3.5*6=21
4*15=60
4.5*5=22.5
5*10=50
Number of votes: 39
Total points scored: 162
Overall average: 162/39=4.154 calculated
4.154 DPreview result

Example 2
1*1=1
1.5*3=4.5
2*4=8
2.5*3=7.5
3*2=6
3.5*3=10.5
4*3=12
Number of votes: 19
Total points scored: 49.5
Overall average 49.5/19=2.605 calculated
2.393 DPreview result

Example 3
0.5*3=1.5
2*8=16
2.5*2=5
3.5*3=10.5
4*2=8
5*1=5
Number of votes: 19
Total points scored: 46
Overall score 46/19= 2.421 calculated
2.233 DPreview result
