Good to hear, have fun getting streetpasses! If you want more per hour, just change the 0-59/6 to 0-59/3 and the 3-59/6 to 3-59/3 that gets you double the SPs.
That should work, have you reset factory defaults and set it up again? Works in some cases. Also, if that doesn't work, try the script in the post above yours.
Thanks for your help !
