When I put that together Monday, I had recalled someone telling me that hearing the entire Bible in three years involved attending every Mass, i.e. attending Mass daily. I couldn't find where I'd heard that, however. What you've described sounds a lot like what I recalled being told. I don't think you can hear the entire Bible in three years by only attending one Mass a week (i.e. in 156 readings). But something is far better than nothing, and more is always better than less!
One former church I'd attended used maybe 4-5 verses of scripture total per worship. Total, and that includes the readings mid-service, and all citations actually provided/read within the sermon! Please note that I do not fault Catholic parishes for their Scripture readings during Mass. I think this is a good thing (Philippians 1:15-18). From my own experience, the only denominations/congregations that provide a regular reading/exposition of Scripture during worship have been Reformed. I can honestly say that I wish other Protestant churches would do likewise!
Calvin's preaching was of one kind from beginning to end: he preached steadily through book after book of the Bible. He never wavered from this approach to preaching for almost twenty-five years of ministry in St. Peter's church of Geneva - with the exception of a few high festivals and special occasions. "On Sunday he took always the New Testament, except for a few Psalms on Sunday afternoons. During the week . . . it was always the Old Testament". The records show fewer than half a dozen exceptions for the sake of the Christian year. He almost entirely ignored Christmas and Easter in the selection of his text.To give you some idea of the scope of the Calvin's pulpit, he began his series on the book of Acts on August 25, 1549, and ended it in March of 1554. After Acts he went on to the epistles to the Thessalonians (46 sermons), Corinthians (186 sermons), pastorals (86 sermons), Galatians (43 sermons), Ephesians (48 sermons) - till May 1558. Then there is a gap when he is ill. In the spring of 1559 he began the Harmony of the Gospels and was not finished when he died in May, 1564. During the week of that season he preached 159 sermons on Job, 200 on Deuteronomy, 353 on Isaiah, 123 on Genesis and so on.
One of the clearest illustrations that this was a self-conscious choice on Calvin's part was the fact that on Easter Day, 1538, after preaching, he left the pulpit of St. Peter's, banished by the City Council. He returned in September, 1541 - over three years later - and picked up the exposition in the next verse.

In three years of Masses you will get the 4 gospels almost in their entirety. (Maybe the genealogies of Mt. and Lk ares skimmed a little. Add to that the two year cycle of daily Mass readings and you've got a heavy NT dose and a decent amount of OT.
Still, important as that is, it won't replace time spent with the Bible and on the Bible.
I LOVE the notion of Calvin's picking up at the next verse after the hiatus! On the other hand, I think devotion MUST include Bible study but ought not to be limited to it and I'm a great fan of the "seasons" of the Church year. So I'm not all about going from one end to the other of the Bible in public worship.
