Suavi,
The bias drift I see is apparent over short time frames. If I do my typical run of 400 or 500 bias frames to produce a new master you can see the values wandering around. So, it's probably the amp glow fix
You have to be very careful comparing noise estimates. The method I use is borrowed from here:
