The nice thing is, starting 120 days out when they go on sale, you can shop the schedule. Lets say I'd like to go from Venice to Florence. Since I like to get out of bed at a reasonable hour, enjoy the hotel breakfast, and make my leisurely way to the station. I'd pick a 9:35 departure. But when I look on line, I can see that only Economy tickets are available on the 9:35 and 10:35 departures, but the 11:35 departure has Super Economy tickets available. That's when I'm going. The early morning trains fill up with business travelers, so taking late morning trains are usually cheaper. You generally can't check into your hotel until 3 pm, so why try to get there any earlier. As with the morning, late afternoon and early evening trains get a lot of business traffic. Late night trains are cheaper.
