I'm using a size proportion variable. If you look at the length of the bat compared to her, it's about 3/4 in size. Then multiply by a certain number to determine a realistic size comparison. The number would be about 5.6. So that leaves it at approximately 4.2. That is approximately my height. And the average human weights about 42.5 pounds per foot. You end up with 178.5. So my original approximation was not very close, but correct in the incredibly heavy theory
