Documentation for IMS PRINT_OPTION ALL outputs

[RyanConway91]

I cannot find any documentation for what is getting written if PRINT_OPTION ALL is specified

For example, what is BACKTRACK FLAG?

Can this get added to the mf6io.pdf?

Have you read through this MODFLOW 6 Framework report? It has information on the numerical solution. https://pubs.er.usgs.gov/publication/tm6A57

I have the same feeling, there is little information of the list file in the documentation. (for instance MODFLOW NWT has some information in Appendix A). For example, I don't know what means *PTC in some iterations of the listing file(Pseudotransient continuation I think is active in every iteration, so I don't know what means its presence in some of them).
