Changing trains at Haverhill

A question: anybody have any idea how many people change from the Downeaster to the T trains at Haverhill to go to stations on the Haverhill/Reading Line? And vice versa?

I'm thinking it would probably be leisure travelers, as opposed to commuters, going to visit family, and the like.

I would assume that it is not many at all. It would take too much time and effort for the average person. From what i have noticed most people who ride the downeaster from haverhill (myself included) just drive to the station and get on the train.
