This is a worksheet I made to help with load development. It's based on OCW theory, but does all the calculations for you. All you have to enter is your desired maximum charge and COL, and it calculates recommended charges for each test group, along with COLs for the second round of development. It's in MS Excel format, please check it out and let me know what you think!
