When adjusted, they came in high and hot???? oh well, they landed....That seems okay?
Taken slightly out of context here.
The reason for the terrain warning was obviously high descent rate combined with terrain. They were always above charted altitudes. A correction, had they done so (they weren't required by SOP at the time) would have mitigated the problem.
So don't blame 'fiddling with the FMC' in this case, at least
