    Hi Aditya,

    Thank you for posting. The calculator results should be close to reality although there may be some slight discrepancies owing to the simplification of  calculations.  The calculator can provide you with a good start, and we always recommend to validate and fine tune by experiment after you build the real circuit. 

    Thanks,
