The drop rate on Floor 99 is not 15%. The 15% estimate is based on responses from 17 people, and that sample size is NOT sufficient to determine with much certainty the drop rate. An update with up to 42 responses suggests a drop rate between 8-15%. So don't be discouraged if you reach the boss nodes about 15 times and you still don't see Mouri. There are others experiencing the same thing.
