I like your commitment to the craft in such a short period of time. Your beers will get better with each batch.
I looked back at the recipe because first time I just scanned it quickly and thought it was something I'd never brew. Honestly never heard of the copper carapils. On second read it appears to be an interesting take on an american red ale. I'd drink it. If it's not exactly what you're going for I'm confident you'll get there eventually.
I think I did iodine tests all of three times and was satisfied I was getting good conversion. My process has been the same for years. I always adjust mash pH and mash temp per style and do 60 min mash and sparge with 190ish water. My results are pretty consistent with regard to that part of my process as long as I pay close attention to water volumes and boil rates. I feel like an electric kettle could help with the boil consistency so I keep threatening to go electric but my system works.
