I have managed a fair few dated parrallels so far. My date distributon follows the same pattern everyone else gets for Etruria - reasonable stable growth, with short wobbles because of civil wars etc followed by steady rise tillthe end of the second century then collapse.
All the villa excavations I could find have the same pattern 0 villas are abandoned at the end of the second century. SOme are resettled say 100 years later or are just never reoccupied.
What is going on? is this the beginning of the C3 'crises or change' ? or is there something about villa economies that don't last beyond 3 or 4 generations? Is that the same for stately homes - often a model for how the highest status villas worked? I keep trying to revisit Brideshead revisted (sorry) Castle then new house then barracks in WW2. what happens then? the sything of the aristocracy by income tax and irrelevence?
