RPS 12th Drive: 13 high weight Ks from the 2000-2300 interval
 

Out of the 126 Ks of the now closed 11th drive we are picking the following 13 high weight Ks to start a new drive:
2043, 2049, 2061, 2079, 2085, 2103, 2127, 2205, 2211, 2253, 2259, 2271, 2289.

The idea is to keep at least a few of the Ks of the former 11th drive alive and above the entrance level for the Top5000 reporting site.
This drive may also be suited for newcomers and/or people with slower machines.

We are starting at 1025k where the 11th drive left, using 2k test files given below.

Happy hunting!
