Command depth keeps the Dogger Bank pursuit moving

Speed is only part of the alternate Dogger Bank result. Four Tiger Cubs would likely have a rear admiral, while six could justify a vice admiral of equal rank to Beatty and accustomed to independent command. If Lion is damaged or signals become confused, that officer can order two cruisers to deal with Blucher and keep the rest pursuing the German battlecruisers. The added command layer reduces the chance that every British ship follows one mistaken interpretation and turns the squadron's numerical strength into sustained tactical pressure.
