How to Change Veterancy/Experience Rate

[katzenbot]

I know similar questions have been asked, but I have not been able to find an answer to this question anywhere. How does one change the threshold for changes in veterancy? I want to reduce the requirements for gaining veterancy, as I find it very hard to get past three chevrons on the normal unit size setting.

I know it's hard to find given how obscurely they named this particular table.
