Would you please tell me if there is any difference in meaning between the present continuous the present perfect continuous when talking about temporary habitual actions? For example:
I'm going to the gym every week.
I've been going to the gym every week.
Kate is binging on TV shows lately.
Kate has been binging on TV shows lately.
Leech Jeoffry in his book named Meaning of the English Verb says that the present continous and the present perfect continuous can be used to talk about temporary habits, but he didn't explain the difference in meaning between the two when used in that sense. Is there any?
