The Dive Timeline PO2 chart is displayed using units of psi (pounds per square inch). This doesn't make any sense. Divers never use psi for oxygen exposure. We always calculate in terms of atm (atmospheres). Typically, the maximum limit is 1.2 or 1.4 atm for the working phase of the dive and 1.6 atm during decompression. Could we please get that fixed?
Here is an example chart from a recent dive showing the incorrect units. (In User Settings I have Unit of Measure set to Statute.)
