Posted below in Fig. 1 and attached at the bottom of the blog is a proposed figure for the RHIC Spin White Paper. This combines the 2011 and 2012 Collins asymmetries, including the most recent ΔR cuts. For an apples-to-apples comparison, we show the 2011 result with ΔR > 0.04 with the 2012 result with ΔR > 0.1 and the 2011 result with ΔR > 0.1 with the 2012 result with ΔR > 0.25.

Note that the results track each other very well for consistent cuts.
