Basically no new big features since the last chart, 7 months ago.
The horizontal scale is in days since today, thus spans circa 5 years.
15k's large quantity of primes is so smoothly spread across the size spectrum
that it makes no visual impact. (An unfortunate fate shared by most fixed-k
based searches, though see below for a counter-example.)
PIES large quantity of primes matches exactly the growth of GFN14 (even though
it's twice as dense), and so introduces no new shape, it simply stretches out
the old GFN feature. The upward blip in the 500 line in the last 50 days is not
PIES, the increased gradient in the 2000 line, however, is.
The 100 line is the most interesting, it shows a large quantity of effort is
going into proper large prime number hunting. Riesel Sieve were probably partly
responsible for that, despite their fixed-k nature.
More mostly meaningless stats when I have time...
