Conqueror can make 30 knots, while the older battlecruisers in its formation are limited to about 24 knots and now run at speeds closer to newer battleships. Grouping them together sacrifices Conqueror's full speed so the ships can operate as one formation. The fastest hull cannot determine a task force's usable speed when slower ships must remain in company. This is the practical cost of mixing vessels with different performance.

Why fleet speed has to match the force
Grouping a fast battlecruiser with ships limited to 24 knots sacrifices its speed advantage so the formation can stay together.
