https://oeis.org/A065421 I don't think the last three (or possibly even four) OEIS terms are necessarily warranted. http://numbers.computation.free.fr/Constants/Primes/twin.html Here we see 1.902160583104... as the value for primes to 10^16 followed by a suggestion that the (final) value "should be around 1.902160583..."

Value for Brun's constant below vs. OEIS value (A065421) is 1.9021605831029730799822614917... 1.902160583104
If the OEIS value is a lower bound then the conjectured formula is incorrect.
