What you state is correct in most cases. However, the jump in vibe may occur with no meaningful time between jump an failure. Additionally, HUMS has always been basically worthless for planetaries. Early report from CAA showed it had a 70% chance of missing a problem or generating a false positive. Since then it has not improved.
Robust chip detection and crew alerts are the best bet to catch a planetary issue. If someone had taken the chips seriously REDL would not have happened.
