The mode of 5.8 on the waist to seat drop is closer to 7 than the chest to waist drop of 4.2. The median of 6.4 and 6.8 are much closer to the target of 7. All of the data suggests the ratio of waist to seat is closer to the standard than the ratio of chest to waist. It would be expected that the recruits that have drops further away from the target would require the most alterations. The mode of 4.2 on the chest to waist drop indicates that the difference between chest and waist runs smaller than the expected.
Further analysis is indicated for the chest and waist.
The ARNscan body measurements were used to calculate the actual fit ease in the first fit garments from T19. The mode and median of across shoulder, chest, waist, and seat are larger than the target. This was taken into consideration when creating the ease range allowed on each measurement. The fit ease target and the statistical analysis of the actual fit ease were considered in generating a range of fit ease for each size in the tariff. Standard design practices and the fit perception indicated from the San Diego data were utilized in determining the minimum and maximum.
