A 2.4-knot margin lets Blücher choose the firing geometry

Can Blücher's roughly 2.4-knot speed advantage really control a fight with Minotaur?

Yes; it should let Blücher keep a long-range chase and bring more forward-firing guns to bear.

A margin of roughly 2.4 knots should be enough for Blücher to control the range against Minotaur. In a chase, six German guns can fire forward against two of Minotaur's heavier weapons. That geometry lets Blücher use the part of her battery best suited to the engagement while delaying the British 7.5-inch battery's entry into effective range. A modest speed difference can therefore shape gun arcs and tactical choice over time.
