So I did an ice bath...
Left thermometer in 5 min, stirred ice, reading just about 31.0F!
For giggles I then took my body temp with a medical thermometer, them used my brew thermometer under my tounge for 5 min and it read essentially the same as the other at 98.5F. So I have to think my high attenuation is sparge related.
