Sorry Db... I get rambling and forget to explain. When you cure you want to jar your product at a certain point before dry and allow a really slow dry in the jar from that point , burping or removing the lid every allows for moisture to escape slower than on a rack or open air.Its very hard to hit that same percentage point to start the cure every time. The scale set to 60%(I use 60 only for reference) will let you know every time when your product has lost just the right amount of moisture and you can now jar your product. Its just a way of making sure you are starting at the same % and the process is the same every time. JAS
