Anyone have any idea how many stops of dynamic range of the A1 can discern?

Anyone have any idea how many stops of dynamic range of the A1 can discern?

8 measurable stops at 0db with broad-spectrum light (i.e. daylight), normal gamma curve. But that last stop or two will have noise and compression artifacts, especially if you try to push them.

thanks, I'd thought I'd heard eight somewhere but could track the number down again.
