Thanks but I gotta laugh. I asked the same question via reply to the short pour email and received this response... The exact opposite of what you just said.

As the hops ripen, the dry matter content increases. Typically, dry matter content will increase by 1% every 4-7 days, depending on the hop variety and the growing conditions. So if your dry matter was 25%, then you should harvest. If you get 21%, then you should wait a few days til you reach 23%. Hope that helps!
