Lloyd,

The 50% has limited useability here, as you don't really start to decompress with any "vigour" until you're shallower than about 15m. You're effectively using the pressure gradient here to elimitate N2, and consequently the 50% won't have much effect on the off-gassing. O2 is a better choice for these dives, as Garf points out.
