The Baalz guides made me take a look at the frequency masks as reported in the 3.17 DB. (Thanks Edi!)

Turns out the most efficient site searching is:

VFB was completely right, I misread the table. So, I removed sites that are alwasy found (lvl 0) and I adjusted % by the number of gems found. So, a site that gives you 2 e is 2x as interesting as one that gives you 1.

n2=22%
w2=22%
d2=15%
e2=9%
s2=9%
a2=6% (never in deep seas iirc)
After that f1,a3, pick you up 2.5%, s3, e3 pick you up 1.3. Rounding due to lvl 0s

So, an N2W2D2E2S2A2 gets you almost everything. A3/F1 depending on design cost.

Now, the fascinating thing is, if you wish to eliminate rares from the equation

W1 - 18.5%
D1- 15.7%
N1 - 15.7%
E2 - 10.5%
W3 - 7.9%
F1 - 7.9%
H1 - 5.26%
w2 - 2.5%
N2 - 2.5%
A1 - 2.5%
E1 - 7.89%
etc.

So all you really need to find more than half of all common sites is
w3D1N1 - Gives you 61%
W3D1N1E2 79%
Adding an F1H1 gets you to 92%.
