I have a couple of questions about auto belays, I wonder if anyone can answer them.
With each decent from an auto belay, you'll fall a foot or two (ish, I'm guessing) before the device catches you and slowly drops you down. I've been doing a lot of auto-belay climbing for various reasons so I wonder if I'm damaging my harness with each drop? It's certainly not as harsh as a big lead fall but its very frequent and certainly worse than a controlled decent off a top rope with a belayer.
I've also wondered how much weight an auto belay pulls. I wonder if it essentially takes a few KG off you? Do gyms adjust the grade of the wall to allow for it or is it so negligible that it doesn't even count?
