Non-GNU rollouts wanted

The positions diagrammed below are positions 362 and 365 respectively from Robertie's 501 Essential Backgammon Problems. Stick said that he didn't fully trust GNU's evaluation of these backgame positions. I did 1296-game supremo rollouts and they agreed with Robertie's verdict of "no double" in both cases, but they were close calls. So I would be interested in seeing non-GNU rollouts of these positions if anyone would be so kind as to perform them.

On a related note, I'm still hoping someone will do non-GNU rollouts of this position that I posted a little while ago, where the GNU rollout was very surprising to me.
