So with the new, updated version of the Trenitalia Pass, booking fees are no longer required and date/time/train changes are free as they would be if purchasing the most expensive Base fare.

We're planning 4 train journeys in 7 days, and it appears this new version of the Trenitalia Pass would save us a good bit of money. Their "4 trips in 7 days" pass is 157 Euros in 2nd class. Here are the fares if bought individually:
Super Economy
- Rome > Naples: 50 Euros
- Naples > Rome: 50 Euros
- Rome > Florence: 60 Euros
- Florence > Venice: 75 Euros
Total: 235 Euros
Economy
- Rome > Naples: 70 Euros
- Naples > Rome: 70 Euros
- Rome > Florence: 80 Euros
- Florence > Venice: 85 Euros
Total: 305 Euros
Unless I'm missing something, it looks like the new version of the pass at 157 Euros would be considerably less expensive, even compared to Super Economy fares, and gives us a lot more flexibility as well.
Am I looking at this correctly?
