Currently the standard calculates the absorption (A72) as a percent of oven dry mass in section 10.5.1 and reports it in 10.6.1.7. The desorption (WLWA) is currently calculated as a fraction of oven dry mass in section 11.5.1 and reported in 188.8.131.52. Because absorption is in % and desorption is a fraction, the users of the standard are finding it hard to interpret the results.
