I'm not race baiting, its really not a lot more nuanced (the popular alternative explanation is the sales pitch made to New Yorkers to get them to buy off on the scheme, because we've taken 18th Century campaign propaganda as unvarnished truth as part of our national cult of veneration of the four ding fathers), and your source doesn't even address the motivations (well, it briefly addresses one participants description of the reason of the change from the Virginia Plan, which had the same salient features and served the same purpose, to the EC, but that doesn't address why the basic alignment with Congressional representation underlying both the Virginia Plan and EC was chosen; the reason, like the 3/5 compromise and the express protection of the slave trade.in the Constitution, was to overrepresent the slave states and alleviate their fears that the long term course was toward abolition), only the mechanics and the history of operations under it.

You provided a source that does not address the motivations for the particular feature at issue at all, much less ascribe them to "more considerations than slavery".
