What are the signs of overfitting in a buoyancy control device?

In the context of buoyancy control devices, the correct signs of overfitting are reflected in difficulties surrounding buoyancy management. Specifically, having difficulty achieving proper buoyancy indicates that the device does not allow for adequate adjustment or fit, which can hinder the diver's ability to regulate their buoyancy effectively. This often results from overfitting, which occurs when a buoyancy control device is customized too tightly or is not versatile enough to adapt to various underwater conditions and diver body positions.

Excessive squeeze can also be a symptom of overfitting. When a buoyancy control device is too snug or constricting, it can create an uncomfortable and potentially unsafe pressure on the diver, further complicating buoyancy management. Therefore, difficulty achieving proper buoyancy, alongside excessive squeeze, illustrates how overfitting can directly impair a diver's performance and safety in the water.

The other options, while they do highlight issues that may occur with buoyancy control devices, do not directly relate to the concept of overfitting as distinctly. For instance, inflation difficulty and excessive drag can indicate mechanical issues or design flaws, but they don't necessarily signify overfitting. Similarly, a complete loss of buoyancy control or frequent tank leaks are critical concerns but are not
