Suggestions for the "Classic Summary" page
Some of us are very grateful to George for reviving this.
I find the "expected new primes" column by far the simplest way of guessing where/when M48 might be found. 1) Quoting George: "Please use sparingly: page takes half a minute to load and hammers the database". Yep. I've noticed that it works things out anew on each visit. An hourly update as per "Status summary" page would suit me fine, and circumvent these problems. 2) The ranges (long obsolete) could be rounded to the nearest 5M with little change to the numbers involved. 3) The penultimate 2 columns are surely best consigned to antiquity! David PS Milestone reached: Expected new primes between 50M and 60M now reduced to 0.391 (same as between 60M and 70M) Last fiddled with by davieddy on 20110609 at 08:28

I have suggested that, or once a day and provide on it the time run. Same thing with the standard millstones page.

Millstones
If the 2000+ milestones were placed randomly* along
Route 66 what would the be the "standard error" of your estimation of the distance you had travelled from Chicago to LA? David *Still ordered numerically of course. Last fiddled with by davieddy on 20110610 at 12:38

We need some kind of distribution....otherwise, all the milestones were all placed within an inch of where they were supposed to be...randomly, of course...with standard deviation 1/3 inch....
Let's try for a uniform distribution of the stones, instead...that might be more interesting...

Call it i. Toss an isided die (singular of dice) each inch of the way from Chicago to LA. Whenever you throw i, put down a millstone and number it one more than the previous one. The number of stones will approximate the number of miles to LA. I know. I should stick to writing songs. David Last fiddled with by davieddy on 20110610 at 20:18

REFEREE!
That was unfair Uncle!
YOU mentioned the "millstone" page. I was trying to make the point that taking the known Mersenne primes as "milestones" was about as useful for measuring GIMPS progress as randomly placed actual milestones. then threw in a simple math question. As for the thread title, I await further comments on my suggestions. I assume George is away ATM. Must be time for another millstone David

This deserves another thread (as uncwilly so tactfully suggested). Where to put it? Oh yes  the "sin bin", "Misc Math". At least it will probably stay put!* Await further developments. David *I hope it won't get relegated to "useless posts by...." in the Soap Box :) PS If you say pick a number between 0 and 1 at random, what "distribution" is the implied/default assumption?
