  "textContent": "I think it is important to emphasize that in my simulation, I used time as a continuous variable with only a random intercept and no random slope. The calculations were based only on _p_\n\nI have attached a PASS report showing an increase in power with more than seven measurements. To reiterate, the primary issue I’m highlighting is the transition from two to three measurements.",
