I have gone through few documents in Google for Present perfect continuous tense and came to know below things.
The present perfect progressive tense has two uses. It is used for:
(1) a continuous activity that began in the past and continues into the present, or (2) a continuous activity that began in past but has now finished (usually very recently).
It might seem a little unusual that an activity which started in the past and finished in the past can be categorized as present tense, but this is because it normally has a relevance to the present.
I understood the first two points but the one in bold font, for which i need example, with clear explanation.
i appreciate your response.
