I think, I have been very inquisitive with this thread. But this affects my training.
I can't train in the sea so I have to develop a way to extrapolate my performance to the sea.
I invented a formula to calculate the score of constant weight in lake.
It's based on the barometric pressure.
This is the formula:
Equivalent Depth=(Dl/0.131 x Bp) x 100%
Where Dl is the Depth achieved in lake in meters
0.131 comes from 760 mmHg/100%
And Bp is the Barometric Pressure at the lake altitude in mmHg
The Equivalent Depth is in meters of sea water.
If we apply the formula the World record in CW in lake and sea, and fortunately the same freediver holds the records, we have:
ED=72 meters/(0.131 x 612.22)x 100
ED=89
As We can see It's not so far from his CW record in sea, so I think it can work.
What do you think, because the lake I train (Is more than I was thinking) is at 3020 meters osl (Pb=505.32mmHg)
sincerely
