How Prince of Wales's readiness might have affected Hood's last battle

Could Hood have survived if Prince of Wales had completed proper shakedown and gunnery training?

Possibly, because steadier fire from Prince of Wales might have distracted Bismarck, but Hood was still lost to an unusually fortunate hit.

Proper shakedown and gunnery practice would have let Prince of Wales maintain a higher rate of fire. More reliable pressure on Bismarck could have distracted the German ship and altered the engagement's immediate dynamics. Hood's destruction is still treated as the result of a fortunate hit rather than proof of one simple, overwhelming armour defect. The counterfactual changes the odds without turning the battle into a certain British victory.
