i feel, for big ranges regularly without calculation. question: twin prime count HOW very regularly? i am an autistic, i love number regularities. please forgive my words many mistake and not good fluent. my brain damage. disavantage: no! may be avantage. we look full picture, sometimes. please think: a few tips: for HOW question. in the special range:exp(n)n^8 to exp(n)+n^8, twin count compare: near other many due prime system: near: cousin prime count, near: sophie germain p, 2p+1 due prime's first prime count =~ twin prime count. sophie prime count %6 or % 8 bigger then twin prime count in every big exp ranges. fluctation %2,5(not:only p in the range), near: G=2*int[int[exp(n)] /6 ]*6 symetric goldbach due prime count (p+q=G, p and q symmetric all primes on point G/2,p and q in the range), near: G=2*int[int[exp(n)] /6 ]*6+2 symetric goldbach due prime count *2, near: G=2*int[int[exp(n)] /6 ]*6+4 symetric goldbach due prime count *2, so: (G mod 6=0 symmetric primes count) =~ (G mod 6=2 symmetric primes count)+(G mod 6=4 symmetric primes count) , this mean =~ : not exatly equal, % 10 fluctational! near: please select (n^8) times 2 randomize integer in the range and look: these two integer same time prime then count=count+1, randomize count*(2,64...) near twin count, near: please mixed 2*n^8 sequantial integer: in the range: exp(n)n^8 to exp(n)+n^8, mixed and mixed. and select two integer sequantial. these two integer same time prime then count=count+1,randomize count*(2,64...) near twin count, so posible come back randomize or not come back randomize: not important! this 2,64... a fix value, every big exponantial ranges! randomize due count and twin count rate: allways a fix value every big exponantial range: 2,64... so: prime system regular base randomize, so:axiomatic, so:predicitive, so:formulative. randomize: not gambling! if we look many big randomize integers, these type systems predictive. math very easy, if think simple, and step by step.  end of text

Firstly, a suggestion: you may want to put your results in a table (in a pdf document, for instance) to improve readability (as it stands, the post is quite long and people won’t want to read all of it).
And secondly, per Tomas Oliveira e Silva, the number of twin primes have been calculated to at least 4*10^18 (about exp(42.833)). You want a twin prime count near exp(88), which is about 1.65*10^38. Yeah, I don’t foresee a calculation of that being feasible anytime soon.

so: every 30 integer only 6 prime test. or 210k{...} (72)*(52)*(32)=15 probably twin so: 2*15/210 every 210 integer only 30 prime test:1/7, 30/210 * (2*88^8)=1,02752721373008e+15 primalize test exp(88)=~1,65e+38 39 digit primalize test only 3 milisecond (poor technic 2019), so: every second 333 primalize test. if we have 10e6 parellel processor then: each proc. only 2*88^8/10e6=719269049 integer so only 719269049/7 =102752721 primalize test. 1,02752721373008e+15 /10e6/ 333/ 3600=85,7 hours if we have 1e6 parellel processor then: 857 hours or 35 days if you can have optimal technic (so:not use poor technic) only a few femto seconds need. math must more groving for primalize test.

please paste: x=10**38+6*10**37+5*10**36;x=n(x);c<=1000;x please press 'only evaluate' button 999 prime search only 2,5 or 3 seconds my very old AMD laptop. (chrome browser faster than other browser, about %250 fast) so every seconds average 333 prime:ok but this technic very poor! please think: how can we calculate, faster 1e8 or may be 1e16 times.

partial look and look: all
if we wonder: twin system how like randomize, how different randomize?
please take two randomize integer in this range: int(exp(44))44^8 to int(exp(44))+44^8. and look: two integer, same time primes than count=count+1 44^8 times loop please. question: count=~? answer: count * 2,64 =~ twin prime count. question: twin prime system how different randomize test system? answer: if we look partial test result: twin system different randomize test? for example: randomize test may be sometimes: 1e5 times no appear same time two prime: but twin system: sequantial 1e5 integer no twin imposible, because: maximal twin gap < 44*44*44/1,32032=~64518 ln( exp(44)+44^8 )=44,00000109311=~44 so, if we look all integers in the range: twin gap > 65000 integers imposible! but 100000 sequantial randomize, same time no appear two prime may be posible, sometimes! quesion: twin prime system how like randomize test system? answer: if we look all test result: twin system count near randomize test*2,64

Assuming I understand you correctly, I created a Mathematica notebook to test this out (see attachment). However, due to timing constraints (I came to an estimate of 9.7 years to run the entire program), I ran the loop for 100 million iterations and then extrapolated to get the twin count. I then compared that to primesieve 7.4 and the number I got was less than 1% off the primesieve value. So in this case your idea makes sense. Some questions I have though: 1. Does this work for larger n than 44? 2. Continuing on this question, what is the asymptotic behavior of doing this if we replace 44 with n and let n go to infinity? Do we get the actual twin prime count, or does it diverge (and if so, does it grow or shrink relative to the actual value)?
