--------------------------------------------
Eye ray generation            (0-2): 2
Cone, cyl, poly isection      (0-2): 1
Shadow                        (0-1): 1
Reflection                    (0-2): 2
Transmission                  (0-2): 2
Shading			      (0-2): 1
Supersampling and jittering   (0-2): 1
Statistics		      (0-1): 1
Exactitude                    (0-1): 1
total                        (0-15): 12
--------------------------------------------
notes:

You have the general idea, but your solution
has some problems.

Your cylinder intersection is not correct.

When supersampling you accumulate the total
radiance, and do not compute the average.

Your normals are wrong, and this accounts
for many of the visible artifacts.
