I don't use sound sequences because I don't want the sound to change if I have a coyote running my way.
I also have a distress sound playing almost 100% of the time. If I am using coyote vocal sounds I will go with gaps of no sound.
If you play a distress sound for 5 minutes and then go silent for 5 minutes you maybe just giving your e-caller a break for 5 minutes. If nothing heard your distress sound for the first 5 minutes then you are no longer calling during the 5 minutes of silence.
During your 5 minute gaps of silence coyotes may move into a area or up on a ridge or hill top where they could have heard your sound if it was still playing.
