Your rating ISO is completely wrong!
Sony A99 has a much higher score than the ISO, which you state your lab tests around the SLT are misleading and reflects micro differences eye and do not perceive the SLT greatly underestimated.

It seems someone painting on the same high ISO 7100 vs A99?

ISO 1600 at 7100 already in JPG visible noise, the A99 anything.
ISO 3200 in 7100 noise is no more evident for A99 small changes
ISO 6400 in 7100 image was far more noisy at A99 level as in 7100 iso 1600!
ISO 12800 in 7100 to significantly increase noise compared to the A99, which is still applicable.

RAW same ...

You write and publish half-truths.
The problem is that the A99 has LOW LIGHT-ISO 1550 but over 2000.

Anyone can look at the samples! and really looking to compare 1:1.

Hello!

Thanks for interest in DxOMark.

The DxOMark sensor score only evaluates RAW image quality on the sensor noise point of view.
The comparison is a JPEG comparison, with a raw convertor that could have slight different behavior between the different cameras.
The ISO lowlight score of the SLT A99 is pretty good and is a third stop better than the last Nikon D7100.
