Well, Dr. just because you agree with one article doesn't make it so!
The Calvinist, Curt Daniel's writes,
When we come to the Swiss Reformation, we find the same view as well (speaking of the acceptance of the Lutherians of Unlimited Atonement), Ulrich Zwingli, Heinrich Bullinger and Wolfgang Musclus all believed that Christ died for every man. There has been debate whether Calvin believed in Universal or Particular Atonement, but the evidence is overwhelming that John Calvin believed with the other Reformers that Christ died for all...Universal Atonement was the accepted viewpoint of Reformed theology up to about the year 1600. Theodare Beza was probably the first Reformer to explicitly teach Limited Atonement. (History and Theology of Calvinism, Curt Daniel, p.370)Vance, however, takes the opposite view and agrees with your view that Calvin was not for Unlimited Atonement!
Unlimited Atonement is a red herring anyway, since the issue is unconditional vs conditional election or is someone saved because they believe or do they believe because they are saved'
That, not Limted vs unlimited Atonement, is the essence of the debate.
