Not owning a sav I didn't pay much attention to the numbers in the first post. After reading a bit on savs today I decided to look at the humidity levels where they are from. To my surprise the humidity map I looked at did not resemble the conditions you mentioned in your first post. It's rarely 30% humidity there. The "dry" season still seldom dips below 75%. Unless I am reading this wrong.
I think the fluctuations are far less than your study. Considering the chance of gout and other issues savs face from dry air I don't think this good for your sav at all. Now if your dry season was 75% instead of the 95% norm there (yuk...sweat city) it might not be badn. I am not a weather expert but the numbers don't match your study. Where did you get your weather data from?
How did you come up with your numbers?
Just curious.
