Not sure what a Stat tour is...expand a bit.
I'll just give my example; maybe it helps. I'm on a 3-year Active-Duty order. The last line of my orders inludes verbage that says the 5-year limit does not apply, that is, I can take as much time as I want.
I don't have it handy now, but if you like, I can forward the paragraph of title 10 that covers this.
