Also, when side decking in and out, if a player intentionally places the cards from the side deck into the main deck in an evenly spaced manner in an attempt to keep them from clumping, is this enough of a violation?

That would only be a violation if he were looking at the cards next to where he was inserting them. Or if they were looking through their deck to see where they wanted to insert the side decked cards. Inserting the side deck cards while face down and not looking at any of other cards in the deck is not presorting.

The main guideline for that penaty (at least unless it gets changed in the new discussions) is if the player is looking at the front or back of the cards. If they are looking at the front, they are presorting, if they are looking at the back, they are just randomizing.
