how to predict wavelength from the chart (BNB USDT )

fırst up wave made 23% and the down wave moved 16%
second up wave moved 15% and the down wave 10.4%
from these numbers we found a pattern

1- 16/23 = 69%
2- 10.4/15 = 69%
3- 15/23 = 65%
4- 10.4/16 = 65%
5- 15*65% = 9.75%
6- 10.4*65% = 6.76%
7- 6.76/9.75 = 69%


from these numbers we fıgure out from first up wave and down wave as u noted the length of down wave is 69%
and the second up and down trend was 69% ,
and the second up and down waves equal 65% first up and down waves
so we can predict next up wave and down wave
next up wave 9%
down wave 6.76%
