To me it sounded like the intention is:
1. good progress: all's good, we are swimming, no need to worry
2. bad progress: things may not be going well, but there is some progress and we need to be watchful
3. no progress: we have been in a bad progress state for too long, and we want to give up and throw an OOM because we are more or less stuck and moving too slowly.

Is that the sense in which these terms are being used in yr PR description? Is something like that written down somewhere in the documentation comments? Thanks!
