Large-caliber Main Guns (e.g. 35.6cm Twin Gun Mount)
 * ★+1: +1 bonus to firepower
 * ★+2~4: +2 bonus to firepower
 * ★+5~7: +3 bonus to firepower
 * ★+8~10: +4 bonus to firepower

So... I shall stop upgading 41cm Twin cannons at lvl 8 or is there some hidden bonus which applies to lvl 9 or lvl 10?
