BTC halving ATH idea

So far, after every halving Bitcoin has gone on to increase in a % value as measured from the moment of the previous halving.

Assuming this trend continues through global financial uncertainty, and assuming the numbers maintain their pattern, and ussiming the price @ halving is the same as today's price, I expect the following:

Bitcoin will reach ±$75,000 in its next bull run, close to end 2022. The next bull run will last approximately 18 months.

This assumption is built on the following observations:

1) So far, every ATH has had a 30% decrease from the previous ATH percentage increase value.
2) So far, the amount of time from halving to ATH, has increased proportionally using Fibonacci numbers skipping the next number in the sequence: ex, 8 21,55 days.
3) The price at halving will be the SAME as the current price (You can adapt this by adding 1000% to whatever the price is at halving. For example if it reaches $4000 by the time BTC halves, the ATH will be assumed to be ±$40,000. This is quite a big margin for error.)
