I'm glad to hear this. I've tried to pose my many queries about Nactation is such a way that they will be of interest to other students of the craft. (Nactation must be a craft, for if it is an art, then I must retire now!)
Here is an example in which a doublet could realistically be nactated with $ (Slot). Up until this 22 was rolled, all moves have been optimal.

Slotting, however, is not the best use of this 22. According to evals by both GnuBg and XG, unstacking is better. Nevertheless, 22$ is an unambiguous Nactation of 13/5.

Here is a challenge for other students of the craft: How would you nactate the better plays listed by these evals? Use the new, non-assumptive, rules for the Nactation of Doublets.
