I have a tool I built in Excel that will project patterns based on range and termperature. I know this has already tried before, but I took what I think might be a different approach to the problem. I expressed everything as ranges instead of numbers. Even when the actual pellect counts are entered, they are treated as ranges rather than individual numbers. That way the tool can create a larger range based on how inconsistant the shotgun/choke/ammo combo is for an individual gun. I think that is the key to making it work. It works on the examples Slicky attached.
Is there someone on the OG staff that can look at this? PM me with an email address and I will send the file an an explaination of what was done. If it works, or can be made to work by the OG staff, I would like to post it somewhere for all to use.
