So far...
My calculation has come to 387 to be the optimal quantity 5 times a year.. but I am probably far off... I know what Wilson is, but i really struggle with the calculation part. No math entusiast unfortunatly, and really struggeling.
3-4 pages in my book with a lot of calculations, and i have no clue how to start, how to proceed etc... :-(
I have googled a lot to read me up.. but stuck :-(
