Bitcoin Mid Bull Run Range Coincidence?

١٧ مايو ٢٠٢١BTC measured from halving date to middle of bull run in 2017 and reiterated into 2021's assumed 'Middle of Bull Run'. Fib extensions measured from the absolute low pre-halving and the local 'mid bull run range's top and bottom' of the respective halving periods. Seems eerily similar though. Not hypothesizing this to happen, just sharing an interesting exercise.
