what I find odd here is that the cubeless equity is correct (it _was_
+0,516 for that rollout) and that the rollout settings are correct
except for the fact that it was a cubeless rollout (it is the only
full 21600, 0ply rollout I've run).

is gnubg reusing older cubeful rollout data?

I'm also wondering why there isn't a Copy-button in the rollout window
for easy transfer of the rollout data to the clipboard (there's only
OK, Stop & View statistics).  I tried to look for the rollout results
being available in another window, but couldn't find any (and the Hint
window looks confusing by now).

I've done one 1ply rollout by now and the result was as follows:

Win     (g)     (bg)    L(g)    L(bg)   Cubeless        Cubeful
0.7104  0,0246  0,0004  0,0779  0,0000  +0,3678         n/a
0,0007  0,0006  0,0001  0,0005  0,0048   0,0018         n/a

(settings: 21600 trials, 0 truncation, cubeless, var. red., rotate
 rolls, seed 11, 1ply, huge search space (8 cand, 0,160 tolerance),
 cubeless chequer eval and Jacoby rule off)
