no, before getting to component plan testing you have to pass gateway
1.401(a)(4)-9(c)(3)(ii)
think of this way. you want to do nondiscrim testing which in some way involves cross testing.
so you want to CROSS into that magic land, but there is a huge impenetrable hedge full of nasty thorns as well on one side. even if you could get to the hedge, you would first have to get over the moat full of nasty slimy things (including Flint water runoff). You tried testing on an allocation basis (which would avoid a gateway) but Gandalf is standing there saying "You shall not pass". So your only choice is to go through that magic GATEWAY. (first and foremost, before proceeding any farther down the road to cross testing land)
hmmm. my copy of the regs says "Lord of the Things", but at least I can slightly understand it.
