1,4

This is the average diving index for those 4k+3 integers in range ]2^n,2^(n+1)] that "dive". See A095101.

The ratios before rounding are: 0, 0, 0, 3, 6.5, 5.714286, 12.933333, 12.548387, 20.691176, 24.635135, 42.903226, 58.98494, 97.742751, 140.742413, 286.896704, 478.786471, 841.487894, 1504.108692, 2788.84881, 5048.608416.

a(n) = 0 if A095091(n) is 0, otherwise a(n) = floor(A095109(n)/A095091(n).

A095360 gives the same ratios rounded to nearest integer. A095355 gives similar ratios computed only for 4k+3 primes.
