So building on this...many physical casinos use a manual shuffle, especially at higher limits, as bigger players tend to distrust shuffle machines. Even some online casinos with live dealers will shuffle the previous shoe on camera, manually.

Since getting a truly random shuffle would take too long, this is a poor method of getting random results. Would it be possible to, at least to some degree, predict the order of the cards using one of these models, given the order of the cards prior to shuffling? I'm thinking something along the lines of being able to say that the odds of a given card being the next one are higher than they should be, not outright predicting the full order of the cards.
