If your Zcash Equihash POW is mathematically sound and implemented (no backdoors) you don’t need to know how the Bitmain ASIC works as your already have a mathematically basis for you POW, based on a sound mathematically reasoned proof.
I am therefore going to assume you are in cahoots with Bitmain to sell mining hardware due to a secret backdoor optimization in Zcash Equihash POW and these system have been mining since around July last year to control the market and all this differing is a delaying tactic as I have said in other post.
NOTE: Signs of a mountebank, differing in giving straight answers to simple questions. Stated in their mission statement ASIC resistant, now not so much.
