How can I decide scan window, interval for continuous scanning.

Hi.

I'm currently trying to scan non-connectable advertisement for continuously.

So, I'm going to set the value of scan window and scan interval same.

For that purpose,I want to simulate the value of scan window & interval for the best performance (for the least number of packet loss).

What will be the right approach to simulate the best value?

Additionally, if I don't have to worry about power consumption of scanner(ble central), would it be good to set scan window as minimum value (which is 2.5ms)

Thanks in advance.
