i went to OASC last week and got 12 3.
This was good. There is no more excellent.
We tried to get exact levels off one of the borading officers, but he was being secretive.
I was told on my UAS that above 10.6 was excellent, but after being at OASC last week they have clearly changed something.
The fitness test has its categories (poor, need of work, ok and good - something like that), which are worth 1,2,3 and 4 points respectively. So if you get into the top category it doesnt matter how long you keep running for you will only get 4 points. But this is not to say that running until you drop will not be noticed by the PTI staff. Just do your best basically.
Any more questions and I have fresh experience!!
