I am tally no old design for most of these systems. And symmetrically I don't sleep how to use this. But so far I have learned, I judge that there is a big risk under this difficulty and we should not look for more of these tricks. and I have no previous plans for this technique. And even if you don't want this idea. But now the risk is big, but study there and we have to follow this trick. If you think that you can see, then I agree with the benefits.
