Cc: techdiver@aquanaut.com
As noted by G, there are two solutions to your problem:

1) Limit dives to 20 minutes.  20 minutes @ 300 feet can be done using
EAN50 and 02 without exceeding 100% CNS Clock.  

2) Start exercising.  there's no need to have a full 40 of O2, even with an
RMV of 0.5 cuft/min (which ain't that great) on the above mentioned dive
using a profile generated by abyss 125. (which is probably pretty
conservative)
