Guys, something to keep in mind (and I’m by no means an expert). I note that when power goes down so does speed and vise-versa. I’m riding “dumb” rollers so I have to pay close attention to % of grade in the app. When the grade goes up I have to down shift to provide the appropriate resistance. I find that if I spin up a hill, my power goes down and so does my speed (regardless of cadence). On the other hand, if I “mash” up a hill, this keeps my power up as well as my speed. In any case, I use my actual road climbing experience to provide resistance in the app on climbs. That seems to do the trick.
