Don't let stress get to you to much focusing on the daily chests. I had that happen the first two days. I got tilted easily and played even worse because of it. Now I am keeping my ECR at 95% + at all times ( I work from home so I play 3 games for some distraction and get back to working ). At the end of the day I end with 90% ECR and wake up with 99% again. Works great and the amount of chest that I get is what it is. Not stressing about getting that extra. You have some high win % days and some lower % win days.
