Naturally, twin primes are rarer, so the gaps between them are more numerous.
I was a bit lazy to finish my range, but new results should arrive this week.
Looking at arXiv: 1807.08777 (J. P. Sorenson and J. Webster: Two algorithms to find primes in patterns), (also jzakiya's program in Misc.Math) I should consider writing my own algorithm in C sooner or later, there has to be a faster method than the one I'm currently using.
