Re: PBT question
In our second to last Nidan test, I ended up catching the "tester" during randori as he passed out (it was at the end of a two hour test). At our dojo the sensei sees you practice every day on the mat and they know what you can do in a class environment. The real test is what can you do under stress?
Of course I know that this isn't for everyone and that's fine. There are other places to train that deliver other things.
