Most cars today don't need an elaborate break-in. Mazda doesn't have a very specific one.
As soon as I drove it off the lot, with 30 miles on it, I took it on the highway and put it into manual mode. From there I gave it several 80% throttle runs in 4th/5th gear up to 4k rpms and let it engine break. I also did one full WOT, which was actually by mistake. I now have 71 miles on it and will drive it normally the next few hundred miles.
