The only conclusion I have is they say if it doesn't last a year, meaning an anode should last a year before replacing. So, if the magnesium one lasts 9 months, maybe an aluminum will last 12 months. Both offer protection, one is not any better than the other. In my feeble mind, it's like putting granulated salt in water and rock salt in water. Both will dissolve, but the granulated will dissolve faster. JMO.

I wonder if the "replace every year"er's replace the anode rod in their S&B house water heater? (By the way, I don't, coming up on 15 years now, I'm just too lazy, and, after this long, probably wouldn't be able to get it out anyway. We're on softened well water, and I have never found any sediment or anode rod "remains" in the tank.)

As far as the anode rod in th TT's water heater, 3 years old, always only use soft water in the FW tank, and less than 25% consumed. At this rate, should last another 5 to 7 years. I'm not going to worry about replacing it until it's over 50% consumed.

Just my opinion!
