While writing to a friend, I attempted to ask which web browser they used most. In the end, I asked which browser they used “more frequently”, but this was not the true object of my curiosity. By using frequently, I effectively asked which browser they turn on more times within a period of time.
I also considered using the term volume, as in, “use with the greatest volume”, but that would have also been incorrect. I would rather use that term solely in reference to cubic measurement.
Specifically, I would have preferred to indicate the sum of durations; perhaps:
Over a period of time, which browser is used for the greatest part of that period?
Is there such a term?
