Dynamic characteristics of program execution must be studied in order to calculate meaningful time and parallel processor bounds. The paper entitled "Time and Parallel Processor Bounds for Fortran-Like Loops" [1] studies only the static interaction between statements within a program to arrive at these bounds. Consequently, very loose bounds are obtained for certain programs. Improved estimates of time and processor bounds are provided for two of the example programs presented in the above-mentioned paper. These estimates are based on an expression of the relationship between operations which calculate values and operations which later use those values as operands.
