They talk about how there is no coherence in organic farming, but there is no coherence in nature. An R-squared value is a statistical measure of a correlation. It measures how much correlation there is between two things. Take humans for example, if there was consistency we would all look the same, but there isn't and we all look different, that's why in natural biology and for statistics an R-squared value of 80% is good enough. The value is a measure of how close each value is to a fitted line, confined farmers probably get an R-squared value above 95%, but organic and grass-fed ones probably get between 80 and 90%, which is "Nature's R". -squared value”. Basically what it indicates is the variability of the data, in this case weight and height, or the distance of each data point from the line in a
