Bug Fixes

• Fixed operator precedence error in calculateAchievablep0(). The denominator inside the square-root in the L0 formula was missing parentheses around (2*k), causing the expression /2*k to be evaluated as ((N-1)/2)*k instead of the correct (N-1)/(2*k). This produced incorrect p0 values and understated the required detectable difference. Thanks to Leonardo Guizzetti, Randy Grout, Christopher Meaney, and Derek Chiu for independently reporting this issue.
