IIRC it was a QM meta-response to me doing the math that Kylinger posted above much earlier in the thread.
e: Went something like:
Me: It'd be around 27 to be Chuunin
QM: Incidentally that's about how much training [it wasn't put into the context of numbers directly in the post, IIRC] Kagome thinks you'll need to infuse skywalkers. You can research them now, with his help, but infusing them would be risky.
e2: Which makes sense, to be honest. IIRC having someone who knows the seal help you with research gets a 2/3 modifer to the TN, and 2/3 of 27 is 18, at which point Hazou would have a 71% chance of not failing. Granted, that's not particularly good odds, but.
