Comment/Request
I want to replicate the formula used in your calculator in an excel sheet based model to produce a ready-to-go tool. Right now I am using both an excel sheet and your web link and for large quantities of data this to and fro procedure is tedious. If you could provide me with the calculations used behind the scene in your website I would be most grateful! Thank you,
