But for 3dMark11 there are submissions without an url. So they are not proved.
One example:
http://hwbot.org/submission/2268692_pixy_3dmark11___performance_geforce_gtx_680_13351_marks
Here's no 3dMark url. Isn't this mandatory?
http://hwbot.org/benchmark/3dmark11_-_performance/rankings?hardwareTypeId=videocard_1913#start=0#interval=20
Just view rank 2th to 7th in the GTX680 3dMarks11 ranking (29 submissions): There is no verification url.
As well as 12th, 13th, 15th, 17th, 18th, 19th, 22, 23, 24, 25, 26, 27
