On your maps, sometime, the Grid MORA does not respect the rule of the safest altitude: 1.000 ft above the ground/sea or 2.000 ft when the highest point is over 3.000 ft in the considered area.
On the attached picture you will see a Mora 9.9 whereas the highest mountain is 9.544 ft, and 8.5 where the highest mountain is 8.123 ft
Generally, on central Italy, your Grid Mora is only ab. 300/400 ft above the highest obstacle, but are correct in the Alps region.
‌Could you explain me how is calculated your Grid Mora and the rule you are considered ?

The first two of your links do not work.

The last link describes how MEF are calculated, and I can tell you that SkyDemon uses a very similar algorithm. Ours should be approximately the same as any arrived at by that method.
