Was the 1944 Eastern Fleet the doctrine's high point?

Did the Eastern Fleet's 1944 raids represent the high point of Royal Navy carrier doctrine?

They were the clearest mature application of the carrier-and-battle-group concept, but not its ultimate test because the expected major fleet battle never occurred.

Jamie traces the Eastern Fleet's growth from Illustrious operating with Saratoga through later pairings with Victorious, Indomitable, and Indefatigable. Their 1944 raids combined multiple carriers with a battle group able to bombard shore targets when appropriate. Alex calls this a high point because the force could apply its doctrine without the earlier pressures, while leaving the expected major fleet battle unfought. Jamie questions whether repeated raids had become the purpose in their own right. Alex accepts that role while maintaining that officers shaped by interwar preparation still wanted a decisive engagement. Operation C returns as an example of a lost opportunity to test that ambition.
