I'm sure you are just too darned modest to say this so I will. Or maybe you don't think that at all.

It's not modesty -- nobody ever accused me of that -- it's tactfulness.
I don't like to tout my own stuff unless fed a very straight invitation to do so. I prefer that folks come to it on their own, or via endorsement from others who can't be accused of shilling for me.
But, yes, some chain care might change the ratio of chainring vs. cassette wear. But IMO the jury is still out on the way to extract the most bang for the buck from drive trains. Some religiously replace chains and preserve the sprockets, others simply run until dead, and some, like myself, rotate multiple chains on the same drive train, then run until dead.
IME all the methods yield comparable costs per mile and possibly the only wrong approach is to run chains slightly too long, then replace them when it's too late for the sprockets anyway.
