Thank you for letting me know this.
Estimation of the simulation time is a more theoretical question and there is no direct guideline in Lumerical website. Using different methods may need different simulation time. I would suggest to use both methods, and verify each other with different simulation time. You can compare the results with different simulation time and see if there is any improvement or change, and the time scale can be 10 times fro one to another to get meaningful comparison.
