DAACS staff aim to produce a seriation-based chronology for each slave-quarter site using the same methods (see Neiman, Galle, and Wheeler 2003 for technical details). Only assemblages from features or stratigraphic groups with more than five ceramic sherds are included in these ceramic-based seriations. Plowzone contexts do not contribute to a DAACS seriation-based chronology. Although two features at the Chapline Place quarter contained more than 5 ceramic sherds (F01=16 sherds; F11= 12 sherds), DAACS was unable to produce a statistically significant seriation-based chronology for the site. However, the site-wide Mean Ceramic Date of 1774 points to the site's temporal placement in the third-to-fourth quarters of the eighteenth century.

Two other measures that are less sensitive to excavation errors and taphonomic processes that might introduce a small amount of anomalously late material into an assemblage were used. They are TPQp90 and TPQp95. The TPQp95 of 1780 provides a robust estimate of the site's TPQ based on the 95th percentile of the beginning manufacturing dates for all the artifacts comprising it. The TPQp90 of 1775 provides a more robust estimate of the site's TPQ based on the 90th percentile of the beginning manufacturing dates for all the artifacts comprising it.
