What''s the usable capacity over the "true" capacity? Assuming the x-axis units are roughly proportional to energy units, the true capacity as measured by where the grey dashed lines intersect the blue curves is 103+4.6 = 107.6 in x-axis units. The display range is 100/107.6 = 93% of true capacity, but the usable range is (100+3.6)/107.6 = 96%.
