Why are you using bread yeast? It will work, but there are better strains out there from the various yeast companies. My one journey with bread yeast made alcohol, but thats a nice as I can be about the the final product. I think that bread yeast just runs until the ABV get to be too much and starts getting nasty. IMO you'd be better off using a clean fermenting yeast strain from White Labs, Dan Star, Wyeast, ect. Thats a pretty high OG for yeast out of a package, I would make a small starter using some honey and nutrient to "wake up" your yeast. Then pitch it into the mead with nutrients scaled to your batch size. My math says you'll be around 12 ABV if you stop at 10.20, thats pretty high and will need to age well, no need to start adding off flavors to the high alcohol.
