Since everyone else is doing it, I had to do it as well. I tested my original props, which have never given me a speed error, and there was some variation in RPMs. I swapped them all out with a new set, and 3 of the motors were closer, but now the right front was high. So I replaced it with another new pair, and now they are closer together. What I am seeing is that there is quite a bit of margin of error for the props, which explains why uncammanded descents were so rare. Even my original props with the largest variation never came close to maxing out in RPMs. And that was with me flying it straight up at max speed sport mode in wind 400 feet. While I did swap out the originals for this test, had it not been for that, I wouldn't have ever swapped them out unless I got a warning from the FW, which is probably the best advice. Even the new props can have variation, but the drone has a pretty good margin.
Here are the originals being pushed in wind...
Then I took them inside for a hover without wind...
Then I replaced all of them with new...
And finally, because the front right was still high, I replaced it with new...
