I guess everyone have the same idea in regards to what went wrong. And like Master Eddie said, spider web, spider web, and more spider web. From personal experience, I've been teaching Cora the spider web for about 3 weeks now and have seen her tap out rate went off the roof. Before when she get an armbar, she struggles to finish them as the kids are very flexible and are able to roll out of it. But after drilling the spider web, its almost a sure tap out no matter how flexible they are. And also a lot of kids kick her head when they panic in her armbar, but now since she do the spider web, she is controlling their legs and thus they can't kick her head. So for the past 3 weeks every armbar needs to come from a spider web.
