“How many of the male posters here learn Torah on a regular basis? “
I do. I attend daf yomi almost every morning and I also am learning Nach Yomi. I also attend occasional other shiurim and pick up other sefarim from time to time (including completing four tractates of Yerushalmi to date not part of daf yomi).
“And how many of you consider the experience of hearing the parsha read in shul to be a significant portion of your weekly Torah learning? “
Yes, hearing it with the trope is important, especially since I’ve never gotten around to learning the trope on my own.
“Additionally, if you learn the parsha on your own during the week, is that a significant portion of your weekly Torah learning?”
Absolutely.
