The Royal Navy already planned to use high-explosive or common pointed capped shells at long range to damage upper works before saving armour-piercing ammunition for a closer finish. That Tsushima-derived doctrine suits a chase in which Goeben is trying to escape two battlecruisers, five cruisers, and a destroyer force. Indomitable and Indefatigable could concentrate on fire while Goeben had to preserve speed and fight astern. Nominal trial speeds conceal a logistical difference: Goeben would probably burn adequate Austrian coal while the British ships carried better-quality fuel. Even a fraction of a knot lost to fuel or battle damage could prevent Goeben from opening the range and make internment more plausible.

The Goeben chase combines doctrine, speed, and coal quality
British Tsushima-style fire against a fleeing Goeben could damage her upper works and speed, while better British coal makes a nominally even-speed pursuit operationally unequal.
