Crossing altitude at LIMMA and Glideslope altitude mismatch on ILS 25L LAX.  The step down altitude at LIMMA (D 7.5 ILAX) and glideslope altitude are both published as 1900 feet. But in fact multiple approaches have resulted in being about 100 feet above the actual glideslope if crossing LIMMA at 1900 feet. This is just enough to cause flight automation to miss capturing the glideslope and instead engaging in VNAV ALT approaching LIMMA; rapidly putting the aircraft in an unstable (high) approach state.
The First Officer reports that the charted crossing altitude at LIMMA on the LAX ILS 25L approach is above the glideslope which creates problems with capturing the glideslope and getting stabilized on the approach.
