most of the math that make up 'stock to flow' metric is averaging a yearly price. .. of averaging a 10 day price
so when seeing the yearly average price line and then saying 'oh look there is a relationship to daily price'... OF COURSE THERE IS
the average is definitely going to be within a 5% deviation.. because the price is only on average 10% volatile (5%up or 5% down)
stock to flow is not predicting anything. its just reformatting a price into a new line thats not the daily price but an averaged price.. so yes ofcourse the line would be within limits of the daily price
if you use a true coin generation/circulation metric. that does not include a price average or any math including the price.. and then set that against the price.. then you wont see the same pattern or correlation
the reason for the S2F correlation vs daily price has nothing to do with coin generation/circulation amounts. and everything to do with the 'average price' math they added into the metric
Also i think that bitcoin does not fit in stock to flow model. Although Stock-to-Flow Model is applied on assets which have scarcity but i don't think bitcoin could follow this model because it is different in nature and also the demand of bitcoin is way too high. Bitcoin will rise much higher as predicted by S2F model.
