The bad news is that meeting the targets for the digit chase tap, the digit chase flick & drag, and the digit chase rear touch panel will not meet the target for this trophy. You've got to shave off another ten seconds from the sum of those targets.
The good news is that you can repeat each of the component games as often as you want. Start with the digit chase tap and replay until you get a score a second or two below the target. Then continue to flick & drag and replay it until you get a score a second or so below the target. Then continue and play the digit chase rear touch panel until you get a score you are satisfied with. I've posted guides for each of the component games that might be of some assistance.
When you finish the third game, check your cumulative score. This is your benchmark. Now, replay the three stages, with a goal of beating your time for each stage. Eventually, you will improve to the point where you have a cumulative score under 60 seconds.
Your biggest help is the third stage because you can completely ignore the numbers. I have initiated the game, turned the Vita upside down before it starts, and tapped like crazy simultaneously on the top left and top right corners of the rear panel. I have ended up with my best scores (under 14 seconds) not even being able to see the screen. Some of this is luck based so don't be discouraged if some of the results are not to your liking.
You may have a stage that you find you are most skilled in. Use that to your advantage. Finally, remember that you have to check your cumulative score in order for the trophy to unlock. You may clear all three stages in 55 seconds. However, if you exit to the main menu rather than checking your cumulative score, you will not unlock the trophy.
