Default I'm doing some gearing calcualtions

I tried to calculate how many teeth there would be on a belt drive Golden Eagle ring. There are some missing teeth but if you lay the belt on the ring. You can figure out how many teeth there would be. I'm getting about 268. I need to count them again in the daylight when I can see better. I'm not going to ask the sellers because I don't feel like bugging them on a minor issue. I want to compare their drive ratio to some others. I searched around a little. I don't see anything mentioned about the gearing on that kit. Figuring 268 divided by 13 would give 20.6 ratio. That gives me the ratio to the back wheel. Thats good enough for a comparison.
