All you have to do is measure two quantities:
1) The total length of the Torah service (or, as my grandfather z"l would insist, seder keriat hatorah; he would argue that there is no Torah "service" in the way that there is a shacharit service and a minchah service), measured from the beginning of Ein Kamocha (or however your congregation starts things off) to the final closing of the ark when the Torah is put away. In addition to the actual Torah and haftarah readings, this includes other elements that are essential (blessings before and after each aliyah; hagbahah and gelilah), conventional (carrying the Torah around the room; Ashrei; prayers for various countries), and complete wastes of time (waiting for olim to make their way to the front of the room; rolling a sefer torah that hasn't been rolled in advance; assigning aliyot that haven't been assigned in advance; the gabbai repeating each name in mi shebeirach lacholim).
2) The length of time for actual Torah and haftarah reading, measured from the beginning to the end of each reading and added together. This will, of course, vary significantly based on the length of the parashah. However, subtracting #2 from #1 should yield a characteristic number that is relatively invariant from week to week in a given community.
My first set of data is from a visit to DC this past Shabbat, and seems like a good place to start, since it struck me as middle-of-the-road for American egalitarian services with full Torah reading: neither the most efficient nor the most inefficient. Please post your data in the same format. It would be great to get data from lots of different types of congregations. Thanks in advance!
