Another area to sieve would be bases with 11 or 12 k's remaining at n=100K. You could sieve those for n=100K500K. If there are too few of those you could go up to <= 15 k's remaining at n=100K. Eventually those will make their way onto the project goals list in future years. Thanks! Last fiddled with by gd_barnes on 20210606 at 06:41

I have added R578 to n=200K to the recommended list. This base is lowweight and is the lowest "relative difficulty" base that we have that is not in the 2021 goals. Therefore it can easily be searched higher.
I am not adding it to the 2021 project goals. Pepi, please have this base sieved by Yoyo to n=500K when you get a chance. Thanks. Last fiddled with by gd_barnes on 20210613 at 06:25
