How do we choose between the present perfect continuous and the present perfect?
Any continuous tense shows us that the action has been going on for some time and its lasting is important. The present perfect continuous tells us how long the action has been continuing.
The present perfect focuses on the result of the action or tells us how many times the action has happened so far.
Jenny is wet and exhausted. She has been running. → the continuing process is important
Jenny has run 10 kilometres today. → the result is important
