Number and percentage of cases where 3D sub-surface areas on each sickle insert in the samples from the two Mounds (WT, ET) were assigned to each of the four plant-cutting groups (domestic ripe cereals, wild-cultivated semi-ripe cereals, reeds and grass).

When more than 55% of the 3D sub-surface areas on each insert were assigned to one of the four cutting groups, the tool was included in that group. When predicted membership in any of the four groups did not reach 55% of the 3D sub-surface areas, the tool was not assigned to any group.
