Maybe having an easy and functional Marking feature will benefit more the Bitmark price than the CEM or the available algos. Once the users start purchasing Bitmarks to mark documents on the  blockchain, then the demand will grow. Most of the users will prefeer purchase Bitmarks than to put their computers to mine or to buy ASICs.

An easy marking and an easy way to query the marked data is the key to put at Bitmark where it belongs (Along with more exchanges having the Bitmark trading enabled).

I would not like to be rude (I do not fully understand all you are talking about the CEM, the algos and their consequences), but you look like perfectionists trapped in the details, without throwing the project forward because it is still not perfect for the next step, when you already have achieved a very very good project.
