True, but I believe you will find, either by doing a force analysis, by talking to the people who build these things, or by experimentation that the weight of the DA pull is dominated by the main spring. Change main springs and you will see a direct change in the DA pull. Leave the mainspring alone, though, while changing rebound springs, and you will see a de minimis change in DA pull (if you are able to detect any change at all).

Hence the "rule," as I was taught and as I have observed for, well, more years than I'm will to admit, as stated.
