Without Anti-Aliasing

Perfect

double size and scaling - 4.00 SPP

Method 1 (old) [+AM1 +A0.1 +R2 +J1] - 4.04 SPP

Method 2 (old) [+AM2 +A0.01 +R1 +J1] - 2.77 SPP

Method 3 (like 2 but mostly using less SPP) [+AM3 +A0.65 +R2 +J1] - 3.73 SPP

Method 4 [+AM4 +A0.5 +R2 +J1] - 4.38 SPP (updated)

Method 5 (like 4 but forcing midpoint always traced) [+AM5 +A0.01 +R1 +J1] - 2.95 SPP (updated)

Test II - limited at about 9 samples per pixel

triple size and scaling - 9.00 SPP

Method 1 (old) [+AM1 +A0.01 +R3 +J1] - 7.26 SPP
