Could Georgios Averof upset the Spanish Navy?

If Greece and Spain had gone to war during Georgios Averof's era, could the armored cruiser have embarrassed the Spanish fleet?

Possibly. Spain was stronger on paper, but its training problems could have allowed Averof to deliver an upset.

The viewer imagines a Greek-Spanish war during the operational era of Georgios Averof. The Spanish Navy should theoretically have been stronger, but the inadequate training exposed by the Spanish-American War makes the paper comparison unreliable. A well-handled Averof might therefore embarrass a nominally superior opponent. The answer makes personnel preparation and fleet readiness decisive parts of any ship-to-ship counterfactual.
