New P-1 CPU credit formula - Page 4

I think I've just found why it looks so weird for everyone - it's a 12x9 image stretched to 15x12.

The stretching distorts and/or blurs the image depending on your browser. If it was replaced with a 15x12 or larger image, (displayed at the same pixel size) it could be sharp and clear for everyone (within limits of their monitor of course). Or it could just be removed and have it all in one big list. Maybe, if it's not already like this, make it so that if people don't have JS it'll automatically all be expanded. Attached is a screenshot of it with the top two changed to display the images at their real size of 12x9. See how much sharper it is? If it was that sharp at either 12x9 or 15x12 pixels, it'd be much clearer that it's a plus (same for minus).

Yes that was the key fact!

3 recent P-1 assignments; all exponents VERY close; identical B1 and B2 however different points. In the order listed below:

1st completed after the formula correction was complete.
2nd completed in the 10 hour window that the formula was not working and had to be manually adjusted.
3rd completed under the previous formula and was adjusted with the auto procedure.

They're all pretty close. I'm pleased!

Close enough for me too. Enjoy the vacation.
