The problem with what Tea is doing is threefold, and as far as I can tell Nanoha almost didn't notice the third.
1) Risky Maneuver; the tactic Tea and Subaru are using is taking a huge gamble, and ignores everything Nanoha has been teaching them. Any teacher would be slightly miffed about this, now you are going to send these kids into combat and the lives of them and their teammates are going to depend on them functioning well as a whole.
2) 110% effort; Tea is straining her powers dangerously to get the kind of performance she thinks needs, much like in military ships (at least the space opera ones) you have your normal max speed, and you an go faster by shrinking the safety margins to the minimum, and hoping that the engine doesn't blow and the gearbox doesn't melt. Now it's one thing to do this in combat, and she has already been told not to take that kind of risk in combat if she can avoid it, and now she does it during a fricking training exercise?
These two points are IMHO why Nanoha gives her the beating, to drill it into her head that what she is doing is stupid because just talking apparently didn't work. Clearly this was a failing of Nanoha as a teacher, she should have explained it better.
and to finish up:
3) Tea has been missing out on sleep and overdoing it in general, just like with Athletes, doing exersizes beyond a certain point does more harm then good. But I don't think that Nanoha noticed that Tea was practicing after the training sessions and missed this one completely till after the beating. At that point Tea is of course taken off the list as active duty combat personnel and told to get some rest, and Nanoha at that point doesn't have to explain the why, and how what Tea was doing was extremely dangerous.
That should hopefully explain Nanohas actions a bit better.
Oh and some people in the Animesuki forum noted a resemblance between the midchilda armed forces and the armed forces of ... dang, can't remember which one, but I think it was Singapore's, where there is a profusion of young Majors and the requits being beaten by the instructors is normal, as well as some other parallels. They made quite the convincing argument about the parallels, which puts it in a slightly different light, if that is part of the way most instructors teach I imagine that Nanoha uses it more as a method of last resort, but it puts quite a different light on that chain of events.
E: "Did they... did they just endorse the combination of the JSDF and US Army by showing them as two lesbian lolicons moving in together and holding hands and talking about how 'intimate' they were?"
B: "Have you forgotten so soon? They're phasing out Don't Ask, Don't Tell."
