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.

25 fps is not that high. I expect it is pretty close to those 28' round
canopies some of you were sitting on and was attached to a Martin Baker.
The old Para Commander (PC), which was a big improvement over the 28'
and 24' round canopies, had a rate of 14-16 fps. So 25 fps is not too
bad, especially when considering that the landing gear and seats etc
will absorb a lot of energy.
