If I need to shift down from the big to little ring, it means I'm in my 50/24 combination. The next lower gear is 34/17, which is just slightly lower. So it's "click the left lever once, click the right lever 3 times".
But since the 34/17 is so close to 50/24, I usually want the next lower gear of 34/19, so it's "click the left lever once, click the right lever twice". No jarring. No drama. Click, click, click.
That’s for at least 3 shifts and possibly 4 to do what a single shift will do with closer range front chainrings. You also have to think about what you are doing and/or keep in mind what your rear cassette count is. Too much to keep track of.
