Maximal gaps between prime decuplets

Prime decuplets (10-tuples) are the densest permissible clusters of 10 consecutive primes. There are two types of prime decuplets:

{p+0,2,6,8,12,18,20,26,30,32} (OEIS A027569, A202281, A202282)

{p+0,2,6,12,14,20,24,26,30,32} (OEIS A027570, A202361 A202362).

The observed maximal gaps between prime decuplets near p are at most log p times the average gap.
The approximate size of a maximal gap that ends at p is given by the following empirical formula:

E(max g₁₀(p)) = a(log(p/a) − 0.2) = O(log¹¹p)

where a = 0.00059 log¹⁰p is the average gap, as predicted by the Hardy-Littlewood k-tuple conjecture.

Maximal gaps between prime decuplets of each type are listed below.

The ratio g₁₀(p)/log¹¹p is never greater than 0.00059, i.e. maximal gap sizes are less than log p times the average gap, where p is the prime at the end of the gap.
