That was easy. Unfortunately, most are not that easy.

I've tested 4 bases so far in this scenario and R947 was by far the lowest weight of the 4. Go figure. LOL

k=2,8,32,34,36,49,71,76,77,79,94 remain at n=25000. Releasing.

With a conjectured k of 100, this base still has 11 k remaining at n=25000. I thought it was going to be 13 until those two showed up today. I don't know of any bases (not including those with very small conjectures) that have had such a large percentage of k remaining.

I like "round" bases
Unconnected,

Are you now done with these 3 bases? Just thought I'd check.

P.S. since rogue is creeping up to it I would like mention that I am working on R998 currently n~= 20.5K
