I can’t comment because I never did this pattern.
I always did 2 per listening day.
This 3 per day pattern works well and simplifies the overall experience.
But as I said, with this listening pattern, I don’t think I’ll ever be able to do full loops of all 3 comfortably.
From experience running only 2 subs per day, I always felt that around 20-25min max total exposure is my limit.
Beyond that, I get overexposure symptoms and the experience becomes more harsh and disruptive which lower results for me.
