It's kinda sad it didn't work out and that's not good for the 2020 rover mission either. Should it be postponed to 2024 to allow to make another landing test flight in 2020.
Measuring the altitude reliably could be a tough problem. A radar can do that during the final descent but before that it may need to rely on predictions. Deceleration should be easy to measure accurately maybe that could reveal if the descent is too steep but I guess there's not much a lander like that can do about it.
