Having given this some more thought, I think your purpose is to show that you have maintained all along that the NDLs for a 25 foot dive would be very, very long. No one has ever disagreed with that. In fact, I said that is likely the reason that there is not a 25 foot level on the PADI RDP--no one would dive that long, so it wasn't necessary.
The disagreement was that you said repeatedly that there is no tissue on-gassing at that depth, and there is no NDL at all. We were just trying to correct that misunderstanding.

- There is tissue on-gassing at all depths until saturation levels are reached.
- At 25 feet, it will take a long time to reach a tissue pressure that could result in DCS, but it can happen.
- Shallower than 20 feet, if all tissues were to saturate at that pressure, the diver should be able to surface anyway.
