The pair of "standard" 25cm by 30cm trauma/ballistic plates(front+back) are indeed only about 1/3 of chest(2*0.83cf of 5.25cf) and about 1.7 times the "vitals" armor location.

So if coverage was listed on that basis it would be something like 1-2 on chest hits+all vitals. But in real life they are much larger part of the front/rear and NO protection from sides(there exists side plates but they are cumbersome).

As example on me the plate covers about the full height of the "chest" hit location and maybe 4/6 the sideways chest. BUT for shots coming from straight ahead(or behind) and you cannot hit anything vital at all. The protection is more like 5/6 of chest area for that, but even slight sideways will increase the danger area.
