Congratulations on that 16.870125 ounces of top quality flower Mark!
And for the record, there is no perfect combo of drying temp and RH for everyone. The key is usually to get the bulk of the moisture out in the first 24 hours (to prevent mold), and then to slow it down so it can hang long enough for a lot of the chlorophyll to outgas. If I had total control that would probably be around 55% RH at the start and 62% from that point on.
Room temp is fine since that's what you'll be storing the buds at, and relative humidity is relative to temperature.
