My rule of thumb George with the DSLR was to use 20 darks for each image processed. As you are taking the darks the temperature will vary anyway so you will finish up with a wide range. Try to match them as close as possible but within a couple of degrees should be sufficient. If you are using a Canon and Backyard EOS software you should be able to capture the sensor temperature in the file name which makes it easy to sort out the darks according to temperature.
