From Lows to Highs % gain - Log scale

Just wanted to show the % gain that has historically been had following the major lows (after previous parabolic highs). This chart shows the % gain (from the major low points in each halving cycle - indicated by the red arrows) reaching back up to the previous all time high.

As we approach $19,800 once again...being so close....just wanted to see how long we could linger below the current all time high. Looking at this chart....I don't see how we could remain below $19,800 for longer than 6 months FOR CERTAIN.
