• If the tension is say X and the tension change is x then the bigger x/X is (i.e drop the tension and that will magically increase) the faster fatigue happens.

    I don't think this is correct. Rate of fatigue is dependent on stress range (x in your case), (provided the spoke remains in tension), not the ratio of stress range to overall tension (x/X here).

    I agree if spoke tensions are low enough that some lose tension altogether under riding loads then I should expect increased fatigue to the remaining spokes. But if tensions are high enough such that spokes remain tensile at all times, then the rate of fatigue should be same regardless of how high your tension is (assuming you are not exceeding yield obviously)

    Problem is the non drive side is normally low, if it gets particularly low, then it is pretty easy to have it with no tension at every revolution
