Does it count if modified it? - Petzl Evolv Adjust

I am adjusting the length of my dogs teathers. Ok one of them I even recycled the rope. I am still counting on the adjuster to do the same task and it works great. Testing different diameter ropes I imagine the weave and material will have some say it as well. It works better than I imagined it would when I saw the product and hatched the idea. I have come to find Petzl makes some pretty cool items
