Even if perfectly tuned they may impact diff. because an arrow flexes as it is shot. When it flexes with a bh , there may be just enough wind resistance or stearing to slightly alter the flight, this is not present with fp' s. It is an inherent design of fixed heads. they fly and group perfectly, BUT impact a little diff than field points.

As stated there are times they hit together - this does not mean the BH is at its optimal tune. Group tune with broaheads and get super tight groups at longer yardages and who cares where fp' s hit.
