I've noticed an interesting property of the 3DS Activity Log: it seems to track less time played than the internal play clock for most titles I've tried on the system.
Take a DS game I recently completed, Solatorobo: Red the Hunter, as an example. Its internal system clock claims a play time of 23:09, whereas the 3DS Activity Log claims I've actually played the game for 16:56 (in hh:mm format). Another notable is the DSi title Shantae: Risky's Revenge, which claims I've played for 5:17 (rounded up) despite Activity Log stating that I've actually played for 2:12.
Which of these reports is more correct? My null hypothesis is that the 3DS Activity Log is more trustworthy -- by virtue of not counting suspends against the play tally -- but I have no data other than my vague intuition of how much real world time I spent to back this up. I would be especially interested in learning how the 3DS Activity Log tracks time spent for each title versus the most common methods used in DS and DSi titles.
Thanks for reading.
