Emphasis mine.

That said, why not purchase a cutter that will cut the tooth profile of something with a larger DP? You seem to have a machine capable of using one.
Our team does overbuild many parts. We used the Lewis gear formula and found that 5.8dp would work well with a high factor of safety. We did break multiple 20dp vex gears in this drive system. The gears are very big and we are looking to reduce to a 6.5dp on the next system we build. The other very important factor for these gears is 100% based on the tooling we have at the time of build.
