• Do Bak, Tang & Wiesenfeld's own 1987/88 papers and Bak's How Nature Works state self-organized criticality's tuning threshold as 'necessary' rather than 'necessary but not sufficient'?

• Dickman et al. (2001) corroborate but do not digit-for-digit match the "0.9488(5)" critical-density figure Watkins et al. (2015) attribute to them

• Does the SOC primary literature confirm that self-organized criticality requires no external parameter tuning and that local thresholds are 'necessary but not sufficient'?

• Bak, Tang & Wiesenfeld's 1987 paper states, in their own words, that self-organized criticality's critical point is reached without tuning any external control parameter

• BTW's own papers state that every local site sitting near threshold is a coincidental feature of the one-dimensional sandpile, not a general signature of self-organized criticality
