Specifications of a Locked Room

As a fan of Golden Age Detective stories I have incidentally read a huge variety of locked room mysteries, even though I don't especially like them more than other mysteries. Occasionally some of them are quite fun, actually, but as you read more and more of them a distinct pattern emerges, and you start just immediately going... Okay, was the murder actually done before the room was locked, or after it was unlocked?

And especially after reading two of John Dickson Carr's exasperating mysteries that are shrouded in heightened spookiness intended to make you wonder whether the solution is supernatural or faked to just LOOK supernatural, only for it to turn out that the corpse was stolen from the locked room before it was locked by the last guy in there, and then that the guy was killed by the last guy to leave before the room was locked (in this case before he was left alone on top of a tower with people watching the entrances).

This must get old even quicker for real fans of the locked room. My impression, without doing any tabulation, is that roughly 95% of locked room murders in GAD are done either before the room was locked or after it was unlocked. This has to take some of the excitement out of it, even if the fan is occupied in theorizing which person did it and exactly how.

And then there's the Sherlock Holmes one, The Speckled Band IIRC. Not before or after but snake!

Yes, I rather count that one as so silly and improbable, but also seminal, that it shouldn't really be compared to the latter genre. But it's usually the ones that puncture the room in some way that are most memorable.
