The link you gave me and I posted, had #ATK (attack chance) of 410 (CA + main), 404 (CA + sec) and 251 (CA main + sec). Test ship levels are between 44~50+. Although the total runs is not as much, but provided sufficient #ATK and the author combined them in the chart. I personally believe it's a convincing test.

The 2 links you later gave me had sample sizes (#ATK) around 110, I'm afraid this will give large errors (~10%) with 90% confidence. So far I'm unable to draw any solid conclusion.

But thank you for searching and sharing them. They helped me a lot and I think it's gonna benefit more players who read this.
