What bothered Collingwood about the signal?

Was Collingwood annoyed by Nelson's England expects signal?

The objection is treated as a complaint about the signal's length and repetition, rather than its sentiment.

Every frigate relaying the message had to repeat its flag sequence. A long signal therefore took time to pass through the fleet. Collingwood's response is interpreted as wishing that Nelson had made the message shorter. This is a practical complaint about signalling, with no need to assume personal rivalry between the admirals.
