You decide. (It would probably require a sophisticated math-
ematical technique called "the calculus of variations" to tell
us exactly how much such an optimum exhaust-velocity program
would buy us.)
Suppose we could find an exhaust-velocity profile that could
raise the kinetic-energy efficiency to 100 percent. Would mul-
tiplying all the minimum-antimatter ratios by 0.6+ (the maximum
kinetic-energy efficiency for constant exhaust velocity) signif-
icantly change the implications of the numbers in the table?
The ratios already seem surprisingly small.
