My sequence is about 15-20 seconds of sound, then stay quiet and alert for 3-5 minutes, then repeat, as long as I am on stand.
Most of the time, I get action on the 2nd sequence, with a bit less action on the 3rd, and even less on the first.
This has worked for me for over 20 years, using hand calls.
I have hunted with guys that switch on the call and let it run the entire time on stand and we did well.
