[QUOTE="Pdvdh, post: 1361559, member: 4191"] The rate values are generalized values and non-specific to outdoor ambient temperatures. A guy would like to think they apply across the most common range of outdoor ambient temperatures, and that might be so, with some or most of the powders. But I tested powders that yielded different rates at different ambient temperatures. This was most pronounced when temps dropped below 35-40F, and worse as temps dropped even colder. From what I've read, a guy might expect the same in really high outdoor ambient temps, compared to room temperature (72F). I presume the rates are most representative within "common" outdoor temperature ranges, say 45-75F. My own rule of thumb is the more extreme my outdoor temps, the more I need to test for my own uses.
