This may confuse you a bit. Skip to the bold for your question. I am going overboard with explanations. Remember that PE had no time of flight for the shells in the original version. Chuck, Blake and myself wrote the TOF code from scratch. We are not mathematicians or physicists. Trying to sync it in MP was even more fun. That was more then 10 years ago.
Check the gun CSVs to verify there is a 24th column. You can view the file as plain text if you use any standard text editing program
and tun word wrapping off. I use CSVed, version 1.4.3 to view and edit the CSV files of PE.
The American 75mm looks like this in Brit44x:

Each line must have a minimum of 23
semi-colons. The code does not require a 24th to end the line. After 23 semi-colons, the game code will use any floating point value it finds. If it does not find a value, 1.0 is assumed.
If there is, then they include data for code work I did to allow each shell to be tweaked so the vertical arc of each shell type can be adjusted. Prior to this, I could never get the trajectory to mach the data and optical drawings that I have. For the optics that had each ammo type listed, this was not a problem in the past. I simply tweaked the optics. I was never happy with the Sherman 75mm until this change. When I finished the guns I needed at that time for Brit44x, I gave my data to Daskal and gave him permission to use it for Redux.
If you got the gun CSVs from Daskal, you should be good to go. If you got them from one of my posts, they are for Brit44x. The gun's data names are not all the same between Ostpak and Brit44.
You can not use Brit44 CSVs in Ostpac. The data names are not the same.
If you did not receive the gun CSV files form Daskel, you can use my coefficient of drag floating point
IF you also use the same shell velocity and weight as I did. If not, you will have to go the gunnery range and spend
hours in debug mode finding the best value for your Vo and Weight. Note: The default optic scale of the guns should also be updated. This value does not affect the trajectory of the shell.
The original optics used by all later 75mm American guns had a 10 Mils cross as a reference point. This cross is 5 Mils in each direction, or a 10Mils cross.
When I made the Allied optics I had no clue what the Mil scale was. I simply looked at the blue print and tried to match it for the shell travel and visual images I had for the optic. I do have drawings, so the proportions of the lines should be close. But, I do not know if my optics are 7 Mils, 9 Mils, 12 Mils or 200 Mils.
If you want to test it's accuracy, you would need to go to the gunnery range and check it. When debug mode is active, all impact data is displayed. This includes the traveled distance of the shell. Note:
All impacts are displayed, so tell your wingmen to cease fire. Once you know the true range to an object, you can make a judgment on the accuracy. If it grossly inaccurate, let me know and I will remake the one
you need. I am more the librarian of PE then the modder these days. Maybe some day I will redo all of them, but I'm not going to redo every optic request for the next 400 posters.
