Honestly, the reading comprehension on this forum is atrocious.
You're the one who's suggesting something magical about the .7 reading, suggesting that a reading around .7 is where the cogs will start being "damaged." I'm simply stating that you are wrong about this.
Parts will wear as you ride them. Sure, the further your chain is worn, the more it may wear your cogs. But there is nothing special about passing the .7 mark, contrary to your claims. When you see the .75 reading, it's a good time to buy a new chain, but the world will not end (and your cassette will not self-destruct) if you ride another few hundred miles.
