So we figure out how to set all three of that type have the same volume and the same long candles filling to study geometric relationship with duration in the light of a candle.
So we figured out a way by requiring that all three of them have an equal volume and wick length equal to the geometric relationship with the duration of the light of the candle.
We figured out a way to the three type has volume rate and filling long candle rate to study geometric relationship with the period of the brightness of the candle.
