My accurite is almost 20% high with humidly (temps were 1.3ºF low...), just saying. I might just have a different idea of what accurate is. I use very very accurate instruments at work and am fussy about it apparently. To me 3% off I'll live with (not happily however...) and 0.5ºF temps is about as good as I'll pay for but I really want better, but I want a BEL more...
