This is ok. I'm sure the temp swing from day to day would be enough for this swing. If it was a 10% swing and in a non drafty area might be worth looking at but that small amount of swing went have any effect on the sticks especially if there in cello. Also if they're fresh they release some humidity and you'll have small swings over a month or so. What size container? What kind of seal? Where is it stored? Can sun or HVAC vents effect it? There's so much that can effect it but it comes down to there's just not much of a swing to be worried about.Tuppedor is acting goofy. Again im running 8 69%rh 60 gram bovedas, and its jumping all over. 69 to 70 and stayed, then bumped to 71 and then 72 and back down to 71....View attachment 123716
