After lookiing at the exif file and the exposure time /f stop, I was disappointed to find that the lighting conditions used would give low noise values not representative of actual use.
The images are really not suitable for evaluation of high ISO low light images, since they were taken under bright lighting of approx ev 10. This will result in lower noise than you would get in low light.
So far, only DPR gets it. Their sample images were taken in low light, about ev 3 which is a more realistic test for low light high iso shots.
This is what I was thinking, it's a brightly lit studio environment. These may be high ISO shots, but not low lighting
