Bro seriously. Am meaning well when I say this. Even I would love to run at least 4 titles in a stack. But even that gives me too much recon. So 9 titles is out of the question.
Now I understand you are asking a question but even 5 or 7 mins of a ZP title is still the full script. Which means that it is still playing 3 titles in a stack when we run 5 mins of each of the 3 titles.
This is why more than 3 titles won’t work even if we reduce listening time.
