Finger Jointed Studs
Most studies involving finger jointed studs were conducted in environment of 11% humidity.
What happens in South Texas environment? Many days over 100 degrees and low humidity. Wood shrink and Detorate pulling loose from adhesive?

It's getting real dry in a home when the RH gets below 20-25%, Before it gets lower than that, someone's going to be buying a humidifier. Checked historic monthly average RH's for Odessa-Midland and the lowest outdoor is 38-40% in March-April.

Re: Finger Jointed Studs
Try looking lower...
San Antonio and below. This area breaks all the rules. Seriously House shopping I found a lot of finger jointed studs were being used in the houses. I grew up in the building industry. I question the use of these studs on load bearing walls. Closets OK. I found lots of houses 5 years old are not holding up well. In one house I looked at the Stairwell was giving in. Behind the sheet rock you could see finger jointed studs that had cracked.

Up where I live, it can get quite dry in the winter. Infiltrating or HRV supplied air outdoor at -4F & 90% RH when heated to 68F is about 5-7% RH.......now that's getting dry.......but the lowest RH I've ever measured in a house was around 23- 25% since house activities, plants, pets, basments continually add moisture to the air.
