What is the maximum processing speed of NIOS II?

true only one instruction can be completed in 6 clock cycles but 19 instructions can be completed in 24 clock cycles(if there are no branches or denpendencies as simknutt has stated) so the amount of instructions completed for n number of cycles would be n-5. so when we are considering a large value of time the -5 becomes insignificant and the effective processing speed reaches 185*6. so wouldnt the maximum speed be 185*6?(mathematically speaking its a limit reaching 185*6 as time increases)
