Exit separation spreadsheet

I read through the latest "45 degree rule" thread recently and remembered that I did the maths for exit separation a while ago for a piece of coursework.

I've attached an excel spreadsheet if anybody's interested. It shows how much separation you'll have on opening with different times between exits, and the different speeds of each group.
All the green cells are editable. All units are in metres and seconds, but I've added a unit converter.
Group 1/2 TV is the terminal velocity of each group. This is used to estimate their coefficient of drag.
Total throw is your horizontal distance between exit and pull.
K1 and K2 are the 2 groups coefficients of drag.

If anybody wants to check the maths or have a look at how it's done, I can upload the write up.
