Dosing seems correct, they established that psilocin (the metabolite of psilocybin ) increases lifespan. The on hand mouse expert likely understood roughly how much psilocybin could be metabolised safely by the mouse. The mice also had some head jerk indicating that they were under influence and they also established that the mice didn't lose more weight compared to the control group.

Some comparisons between animals and humans just aren't compatible with understanding dose and volume. Some smaller animals eat their weight in food, I just wouldn't recommend basing your own dietary fiber intake on that.
