I actually like looking at data that is 1-2 years old, so I can see what the management was saying during that time and fast forward to now, seeing if they actually implemented their strategy and the financials improved accordingly. I also like 10-15 years plus of data because I want to see how a business operations through a full business cycle (peaks and troughs). Most recently, I am most interested in how management works through COVID (2020s), which is out of their control. Or in your scenario above, a weak yen. In due time, there will be a stronger yen.
As for the 2024 version, It's like looking at a chess board and seeing the optionality. If you're given the same data as Warren Buffett and don't see the "play".. then oh well.
It's like working with quarterbacks and asking them what they see during their reads.... Tom Brady and other elite QBs will see stuff pre-snap and post-snap that the Bryce Youngs of this world will not see. You could run into "resulting" like Annie Duke.. but, I still think it s a good table top exercise.
It's a regression testing on your thought/investing process. If you can see the fat pitch then, you should feel confident in applying the same analysis to the current 2026 version... if it's still available.
