You are welcome! I think there's an error in your math somewhere. Getting some kind of rail pass will almost always save money, unless one is doing only one or two trips and no mountain transport. Likewise, the Good Morning Ticket for the Jungfraujoch is only beneficial to people who do only that trip, and no or little further traveling in Switzerland. The price with a pass is much better, and there won't be any time restrictions. If you do buy the Good Morning Tickets, I am quite sure you can take a break at Kleine Scheidegg, as long as you take the 1 PM train down from the Jungfraujoch. Their goal is, I guess, to spread visitors equally over the day, so they want the early visitors off the mountain by then :-)
A regular ticket from Grindelwald to the Jungfraujoch is not CHF 197.60 (that's the price from Interlaken Ost), but CHF 177.00. With a Swiss Half Fare Card it's CHF 88.50. A Good Morning Ticket is CHF 135.00.
As for the rest of the math: you may have retrieved the wrong prices from the timetable. It's defaults to half fare (because most travelers do have a pass) and a single trip. You need to click further to see the full fares, or just multiply by 2 for a single trip, and by 4 for a round trip. It's explained on the timetable page.
I think it's worth it to check again. You'll most probably end up spending more and limiting yourself with the Good Morning Ticket if you don't get a pass.
I hope this helped!
