This drastically understates the coverage of the New Testament in the bible by the mass, because it doesn’t take into account parallel readings. I did a similar study myself, and found that there were only a handful of gospel verses not used in obligatory masses.
Also, it should be noted that those verses which are cited by the New Testament, as well as the context surrounding them, are the portions of the Old Testament used by the New Testament. A well-crafted homily should explore how the New Testament fulfills the selected Old Testament verses, examine the moral doctrine espoused, and provide some guidance in applying it to our lives. Unfortunately, there is a crisis of poorly-crafted homilies in the modern church.
I would be extremely cautious of declaring that the Mass has covers the bible insufficiently. For hundreds of years after Christ, the canon of the bible was simply those books were used in mass. Given that most Christians were illiterate, and that bibles typically cost several years’ wages (picture a two-hundred thousand dollar bible to compare that to modern times!), ancient Christians laymen’s exposure to the bible consisted largely of what they heard in masses. Even priests often could privately access only a “breviary,” which consisted of the gospels, letters, and Old Testament canticles (by which was meant the prayers and songs of the Old Testament, including the Psalms). (They certainly had access to a full bible during their studies.) Yet, I’m sure we should literally be put to shame by their piety.
On the other hand, Satan had not so thoroughly corrupted supposedly Christian society. Christians today require both a childlike faith but also a wisdom of understanding of theologians. So the Catholic Church was quite correct in joining Protestant churches to insist that Christians indepenedently read of the scripture daily.
I'm counting the First Reading, Psalms, Second Reading, and Gospel for Sundays in these Stats...

Perhaps I am fortunate, but my priest pulls on the typology between the First Reading and the Gospel all the time. He also realtes it to our present days lives and puts it back into our hands with a poignant question at the end of each homily. (Some are totally teaching ones, of course,) He just did a complete sermon on the vesting of a priest for Mass and all the prayers that are said. It was great!
