I have this chart I've been making to drill learning general Agency-Mood-Tense grammar. The primary issues I've been running into is that there are a significant amount of examples that somewhat disprove the premise of tenses I have (past, present, future). Another issue I've been having is wonder, is it even worth spending time practicing with some (Subjunctive I or Konjunktiv I, for instance). Other times I struggle with wondering if certain examples just aren't used often in spoken or in written form (Passive Future Perfect).
I'd like to have a chart that I can rely on that explicitly points to an example of "This is how you would be expected to speak/write in German in whatever form of Agency, Mood, and Tense" so that I at least have a scenario to work with.
Are any of these used for a particular reason over another. Like in spoken German, is there a reason you'd utilize the Imperfect Past over the Pluperfect?
Also, are some of my examples just flat out wrong or incorrect? As I've been using this, I've discovered some of these are incredible niche cases that are rarely ever utilized in preference of something easier or more colloquial.
Caveats/Concepts I'm currently aware of:
Imperfect is reserved for the written language. Modal verbs take the imperfect form in both however (nobody says/writes "habe gekonnt" or "habe gesollt").
Subjunctive I is reserved typically for newspapers and broadcasts "reporting" on behalf of others.
All of these are "Semi-Modal" verbs [ Bleiben, Brauchen, Fahren, Fühlen, Gehen, Helfen, Hören, Kommen, Lassen, Sehen, Spüren ]
