Have you tried to go a bit lower on your limit, say 1.008? and see if you notice it. By all means i know i shouldnt ask you especially:) but from my understanding two things result in tannin extraction high PH and high temp. So if PH is 5.2ish and temps are good maybe one may not have to worry as much about tannin extraction?
I say this because i had the same issue with my EHERMS, seemed to be extracting all the sugars prior to sparge and always ended up short. it was very frustrating so i just sparged anyways to 1.008. No one including myself notice off flavors related to tannin/Husky extraction (pilsners).
If that is working for you then don't change anything.
Well I think I really need to pay better attention. I really don't enter companions much and there is to much room for error with my and my homebrew clubs palate.
