My total now _does_ seem to be 6 seconds long after all. I was right for my subjective time being about the 4 seconds (with 1 second ramp up and 1 second ramp down for a total of 6) I tried a metronome at 20bpm which is 3 seconds apart. and I could easily remember. 4 seconds (15 bpm) apart and it was tenuous and I was losing my grip of the timing but I could keep it. But at 10 bpm, which is 6 seconds between beats, I mentally completely reset. I forget about the beat that was just there. So that’s my total now. 6 seconds. However, I will try between 10-15 bpm to see the crossover point. https://www.youtube.com/watch?v=OmIOg6RQoxQ
