However, in practice BCS is not well-suited for that purpose. For one thing, each application after the first one multiplies the number of simplices by formula_46. BCS also multiplies the degree of each original vertex by formula_47, and the degree of each edge by formula_48. Moreover, the BCS will split all simplices, even those that are already small enough. Finally, each BCS stage also makes the simplices not only smaller but "skinnier", i.e. it tends to increase their "aspect ratio" (the ratio between the longest and shortest edge). For all these reasons, in practice one rarely applies more than one round of BCS, and other subdivision schemes are used instead.
