So, I mentioned that when I had to reboot poltarcc I had to reset the ESR 4K coolant return temperature max to 100 so it wouldn't alarm. It went over 100, so I set it to 105. I looked closer at the target screens I've been posting when the 4K flows dropped and realized that it started at 80 something and has risen to 100K. Greg mentioned that is was oddly high to me so I wasn't too worried, but it's steadily rising still.
