Pangya Season 4 Calc by hand

[h40]

Hey all, first post bare with me.

I really enjoy playing pangya, and the challenge of not ALWAYS getting HIOs/Chipins. But...I know all the pros and non-hackers still use a fairly simple equation with sine, hwi, distance, elevation etc...

Edit**Is there an existing thread with an UP TO DATE, good list of HWI for 246/248 distance, and maybe a simple guide to learning how to calculate by hand?

Thanks in advance guys
