Shifting anytime after power drops off, will result in being slower to accelerate. Since that graph doesn't have any rpm designations, I cannot comment on it specifically.
for fun, I just checked an acceleration vid of an e92 m3 with DCT (extremely short gearing). the RPMS dropped by ~2200 on the first to second and second to third shifts.

point remains on the f80 m3, shifting at higher RPMS will result in more average power since the power is flat for 2000ish RPM and does not drop off according to BMW.
