position of adverbs

[navi tasan]

Which are correct:

1-The data is entered rapidly using this method.
2-The data is rapidly entered using this method.

3-The data is entered more rapidly using this method.
4-The data is more rapidly entered using this method.

I always use 1 and 3 (the adverb comes after the verb) but I don't think the other two are wrong.
I wonder if changing the position of the adverb makes any difference.

[Anglika]

Not really. Both are acceptable.
