I want to know the meanings of the following sentences:
- John missed at 50 yards.
- John missed by 50 yards.
Does #1 mean that John missed (a mark? or what?) at the place 50 yards in front of something (a mark?)?
What does #2 mean?
According to one explanation I read somewhere, #2 means “how far I am to the side of something”. But I don’t know what they mean by that.
Does #2 mean that John missed something at the place 50 yards away from something?
