If 4d6dl is the baseline, what's the PB/Array?

Ok, if anyone was interested, here's the graph of the data for what 4d6 drop lowest yields. As was pointed out this does not take into account rerolls. The 2nd-5th positions were found through Brute Force Monte Carlo (100,000,000 points)

The average stat array then is:
15.66, 14.16, 12.93, 11.73, 10.38, 8.50
--16,14,13,12,10,9

Just to get an idea of the effects of rerolling, if you use the 3e rerolling rules (modifier total <1 or max ability < 14) these become:

15.95 14.45 13.23 12.02 10.66 8.72

You can see how the 3e "elite array" is just these rounded down:

15 14 13 12 10 8
