EDIT 29th Aug 2020: We now REALLY want to get this mod done, and a friend has volunteered PAYMENT up to a certain amount to get this done. Once complete we would expect the mod to be kept up to date and it WOULD be given to Aslain for possible inclusion in his modpack. I am serious - a PAYMENT is available for someone reliable to make this for us.

========
I would like to suggest a mod that calculates the percentage accuracy of each shot taken. It would display a %age on screen, where if the shot lands on the outside edge of the aiming circle, the score would be 0%. If the shot landed exactly on the crosshairs it would display 100%. Half way in between the crosshairs and edge of the aiming circle would be 50% and so on.
EDIT: Ideally, this mod would have an option to save data for each shot into a CSV formatted file for data analysis at a later date.
The reason is that this would show the true accuracy of guns as in what we get after the unpublished soft stats etc are taken into account, and not just the "published" accuracy stats.
