-When changing the altitude in Baltic, the generated plan is still computed assuming salt water and sealevel pressure when computing depths. This means that the plans are suitable for using gauge that's calibrated for ocean diving, not a gauge calibrated for fresh water and with a surface pressure of less than 1bar.
