It's impossible to "compare notes", since you have quoted all sorts of numbers, but no actual answers.
Angela S's answer is corroborated by telescope observations. Under excellent seeing conditions the smallest details visible on the Moon are 1 to 2 km across. A good example are the 4 small craters on the floor of Plato, which are 1.7 to 2.2 km across. To see them requires near-perfect seeing and an excellent telescope.
When two completely different approaches come up with the same number you're probably on to something...
