I have had my Nintendo 3DS for almost 2 days now and at the same time my bro has had his. In about 40 hours of us both having StreetPass set up we have tagged 5 times. After some testing I have determined it retags every 9 hours, although it varies a little (not much), but I think that is related to how far our DSs are from each other based on where we each have them in the house, etc. when we can retag again. The time for retagging might vary based on the specific Mii???
The first time we tagged was about 4pm. We both left our 3DSs in Sleep Mode overnight and in the morning we had tagged again. Then around 10am yesterday we tagged a third time. We tagged a 4th time around 8:30pm last night and then a fifth time this morning around 5:30pm (I believe we did not tag automatically overnight this time because our 3DS were on opposite sides of the house and the first night they were in same room).
I kept reading it could only be done once a day per system you tag, but that is definitely not true. At first I thought it was every 10 hours, as that best matches up with the different timing of our tags. However, after more testing and paying better attention to the tag times I am pretty sure it is every 9 hours, although their is a slight possibility it is random between 8 and 12 hours between tags.
I am glad it is more than once a day, though, as that means I get to use him as a hero to further my progress in Find Mii without having to buy heroes. Plus, he levels up every time we tag and thus is more helpful.
