I pray that I'll never need to use one in a self defense situation, but if I do, I hope I'm carrying enough ammo!
And yes, I shoot all of them at the range on a regular basis. If I start having issues with one, then it gets removed from use.
Agreed. I think that this is the meat of the issue. Test what you use, use what you test. Increasing or decreasing the number of tested items doesn't change or alter which specific one might fail during EDC. More feels better because it appears that we're spreading the possibility of a failure across multiple magazines. But that isn't how it works. Each magazine has its own probability of failure. That probability is not shared with the other magazines tested.
To me, it doesn't matter if you use one or five but put all of them through the pistol from time to time at the range. My only thought about having more than one, if possible, is to ward off fatigue within the parts from use. (Because shooting is fun and we should be using our stuff all the time for the joy of it.) But for a quality firearm and magazine metal fatigue (or tactical plastic these days) should be years down the road anyway.
