Time analysis: Could the bitcoin bear market end October 2020?

To me, it looks like the market is moving slower after each cycle. Our last bull run was longer than the previous one. The 2014 bear market was also longer than the 2011 bear market.

To my findings, the bear market of 2014 moved 2.5x slower than the 2011 one. If we use that same factor this time according to my calculations the bear market now should end around October 2020.

I know that sounds very depressing but as a long term trader I'm trying to find every possible outcome and this is one of them.
