SI-1 for example works fine with one full bottle the first use a full bottle every 3-5K or 2-3oz or so every full tank.
Do the injector coils even come in direct contact with the fuel, aside from their coating?? Seems to me that the coils would need to be continuously bathed in a fairly strong solvent to cause any kind of shorting between wire turns. I don't see how this can happen using a pre packaged injector cleaner??

No they don't, the fuel passage is separate, the injectors are basically just solenoids. The core on the shaft inside the fuel passage can get corroded or stick due to varnish hindering its movement but most of the time they can be freed.
Corrosion mostly comes from moisture and varnish especially in older iron and brass units that did not take alcohol into consideration. You find varnish in units that sit a long time with old fuel.
