Inaccurate strike temps – Sparge Pal Review

This underestimates strike temps. I undershot my mash temp by 10 degrees and had to do a mini decoction mash to get it up to a reasonable temp. The batch will probably be fine but this added about an hour and a half to my brew day. Will not use again. Interface is fine, would love this if the calculations were correct.
