T or NIL

(setq grading (tingr:createTinGrading '(0 0 0) '(100 100 100) 100))
(tin:addPoints grading '((10 80 5) (50 50 10) (10 10 2) (80 20 7) (70 60 3) (40 70 10) (25 25 6) (55 55 2) (75 45 5)))

(setq refEntity (entlast))
(tingr:setSlopeRule grading refEntity 0.5 2.0)

Remarks

after creating the grading entity, before it is fully parameterized (see tingr:setSlopeRule and tingr:setSurfaceRule), there might be harmless warning message sat BricsCAD commandline
