Well, as people know i run my gunners light and burn off excess experts to the point I can tweak my rookies to get to as close to 100.00% of the reload cap and only marginally above the accuracy cap, as opposed to having 300% accuracy and 140% reload or whatever.
I've noticed in static ( not moving) firing tests, the spread inmproves marginally when your gunners' ability are this way. Depending ont he nation/gunset for some it tightens the spread far-short, for others it tightens the spread "width" ... I think in the Kaisers' case, it tightens the spread width but still gives the far/short max range shots.
In the few times I've played it in GBs.. I've had to say the Kaiser gobbles up L2s easily where an H44 used to struggle (esp against AWs) .. its the small ships that hit hard and "catch" up to you like Griefer mentioned, despite the 37 kts.
I always wondered what giving it 38 kts would "do" ... esp in a GB.. Might let you smack the smaller rushers once more. It is similar to the H44 in that it is a "react" ship. If you're lagging and cannot run once the enemy has actually commited to turning in, you're dead.
