I sent Maukka 2pcs 4000k in the production batch for him to test, and here's the report for both pieces:

Summary: Slightly above BBL, but not wildly out of control. This report suggests that the stock I have is very different than the ones tested in the L6 FC-40 thread.

At 3 A: +0.0015/+0.0019

At 1A: +0.0023/+0.0026

Note: The sample is presumed to be tested without lens. Most AR-coated lens will bump the duv values by about +0.0020.
