Figure shows the same data in the form of a histogram of the ratio between measured and geometric pore volume. As the geometric pore volume will overestimate the measured value, and considering some uncertainty, one would expect those materials that are fully activated and nearly fully crystalline to fall in the 0.75-1.1 range for this measured/computed ratio. It is encouraging to see that we observe a peak in this range, accounting for ≈35 % of the measured pore volumes. However, the majority of materials falls outside this range.
