3 halvings, so N=2 (number of pattern repetitions). It is far from enough to proceed with such certainty and ignorance of all other factors. In a cointoss game the probability of calling 3x heads in a row (or tails three times) is 1:4 and yet to the inattentive observer the conclusions may be: 'so far it has always come up heads, so I assume that tails can never occur and I'll bet on that all my money ignoring the fact that another side of a coin exist".
it should also be noted that correlation does not imply causality and it is impossible to judge causality on such a young and volatile financial instrument with such a small sample.
Returning to the halvings, each subsequent halving is different and from a fundamental point of view it is advisable to expect an increasingly weaker impact on the valuation because:
1st halving was important. It reduced monetary inflation from 25% to 12%. Thats a big deal. Second halving decreased monetary inflation from 9% to 4,5%. Now we are getting closer and closer to the 4th halving that will reduce bitcoin monetary inflation from like 1.5% to 0.7%. Both numbers are negligible compared to 8% official CPI in US, 10% in EU or 80% in countries like Turkey. So my bet is that halvings fundamental impact on bitcoin price is getting lower and lower with every next halving in oppose to macro data, FED decisions, interest rates, recessions etc. Bitcoin will be more like an asset that act sometimes like gold on steroids sometimes like sp500 on steroids rather than it will fallow "bubble x days before each halving scheme"
Also the characteristics of the average investor in 2012 are completely different than in 2023.
