Neutral point calculation

[nevinm123]

Hello freediving friends,

I am trying to calculate (theoretically) the neutral point of a freediver without any wetsuit.
Can you please have a look into my calculation and let me know your thoughts.
Thanks in advance

Your assumption about "10% decrease in lung volume with depth" is way off. At 10 meters your lungs are reduced by 50%.

I agree,that was not correctly written. But if you check the formula, at 10m the lungs volume gets half

Why not just get in the water and try it out? Dive until you find your neutral depth. Surely that's more accurate than a calculation?

Yes, i agree.
