A DH1 Packet need 1 time slot for transmitting and 1 time slot for receiving. Then the system makes worst case 800 hops per second with 79 channels. So you have each channel 10.13 times per second and so for 31.6 seconds you have 320.108 times of appearance. Each Tx-time per appearance is 444.89μs. So we have 320.108 * 444.89μs = 142.41ms per 31.6 seconds.

So you have each channel 5.1 times per second and so for 31.6 seconds you have 161.16 times of appearance. Each Tx-time per appearance is 1.7ms. So we have 161.16 * 1.7ms = 273.97ms per 31.6 seconds.
