The references below to the PC, 24', and 28' parachutes are round parachutes.
The 28' round was used in the Martin Baker extraction system system. I was not
comparing any round parachute (like the BRS) to the square parachutes used
today.  I was simply stating that the old 24' and 28' rounds have decent rates
that are probably similar to the BRS decent rate.  Sorry if I was unclear on
that.
