<comments><![CDATA[based on CAR thrust curve & cert letter
received from WestCoast/Scott Harrison
compiled by RockSim EngEdit
hand entered data points from CAR thrust curve
approx 10% higher total impulse than cert letter
approx 5% higher total impulse than thrust curve
within a couple percent for peak & average thrust
accurate thrust profile
