I've revised the OP to include Effective Mass vs Ranking for both ATP and WTA players.
In summary, the higher the effective mass of the racquet, the better the ranking. This is true for both men and women.
And for both men and women, there appears to be a big performance drop-off when effective mass drops below 160g.
To calculate the effective mass of the frame, I used:
Effective Mass = M/[1 + M*(b^2)/Ic].
M = Racquet mass.
b = distance from balance point to impact point (assumed to be 12cm from tip) = L - 12 - R.
L = length of racquet
R = distance from butt to balance point
Ic = recoil weight = SW - M*(R - 10)^2
