All ranks the same

I am currently gold 1 just lost my plat promos unfortunately, but have been getting paired up with low to mid plats and I noticed something. I only play adc and I ended up playing on a smurf in bronze which I only do occasionally I also have one in silver. I play the exact same in every elo, my scores don't really change, from bronze all the way to high gold and low plat I perform roughly exactly the same in the adc position. I am curious if anyone else has had a similar experience?
