I know the basics like staying on an axis, placing a block trail, etc, but I always struggle after the first few throws. I usually throw my second eye 1400-1600 blocks from spawn, but after that its very hard to know how much further I should go until another throw. Because of this, I throw a ton of eyes in close proximity to each other until one goes straight down. Although this is my main issue, overall advice would also be great. Thanks :)

I couldn't find data anywhere else online about how long the dragon could circle around during the fight, so I collected data myself and wrote it down on paper. I decided to move this to a google doc to clean it up, and am posting it here hoping it can be of some use to others. https://docs.google.com/document/d/1MdWi9f7W1JZc0LEpVeUsSnKDX4qZ1HzkdgiM5UBnCWM/edit?usp=sharing
