User blog comment:Fujihita/Design of Experiment: 20.3cm (no.2) night battle accuracy bonus test/@comment-25637142-20150922035233

Okay, so we have a few things we need to address.

The major issue now is the blocking factor "+1 visible acc bonus" on no.2 gun. I certainly want to block it out of the equation but the only way I can see it happen, without introducing more lurking factors to the system, is using the 14cm main gun.

On the other hand, a direct comparison between no.2 and no.3 guns can be more useful. The test would not be about the yasen acc bonus of no.2 but it would be about whether no.2 gun with its visible acc (regardless of its own hidden acc bonus) can outperform no.3 gun (assumed to have hidden acc bonus) or not. However, it wouldn't be possible to draw a definitive conclusion in regard to no.2's hidden bonus with a test vs. no.3

The other thing is the test location and the subject of the test as discussed below.
