This question should only matter when you are first joining to ensure you meet that minimum. You should never need to ask or look at the minimum ever again.
You should only care about the maximum. Everytime you take a PT test, you need to try to max it out. It should be a point of pride and it shows you really care about fitness and doing your best. This mindset will help you in your military career more than just for a PT test.
Why would you not want to try to be the best?
