Terry Laundry used to make his "Ringing Cycle" lengths based on the time span of dramatic corrections followed by secondary corrections.
I played with that and didn't find a holy grail exactly, (and some "inversions") but did notice some significant high volume bottoms that aligned with the imposed cycle lengths.
Recently I tried that with the last 3 bottoms and got a mid-November confluence or the 2 cycle lengths. TWT:
