Qiskit, I tried to estimate circuit runtime using gate_length from Backend.properties()
but its accuracy is very low (real system is 3.5 seconds, estimation is 0.00002 seconds). So, are there other ways to estimate circuit runtime? I think this is very important because if I want to run a circuit on a real device (pay-as-you-go), I need to know how long my circuit will take before submitting the circuit.
