Another atypical entry - a diagram from The Journal of Inductive Biblical Studies 1/1:22-58 © 2014 Asbury Theological Seminary Major Structural Relationships: A Survey of Origins, Development, Classifications, and Assessment by Fredrick J. Long that gives a view up to 1965 of the range of inductive Bible study ... and perhaps can give a bit of a push to the Jensen pre-pubs: Irving L. Jensen Collection (24 vols.) and Independent Bible Study

Note: the article itself is quite interesting showing the "history" behind several of today's hermeneutics/Bible study texts' identification of units and their relationships ... and, yes, it includes arcing.
