Let's get a closer grip in present and past growth of Mt. Everest:
In 1856, Andrew Waugh announced Everest (then known as Peak XV) as 8,840 m (29,002 ft) high, after several years of calculations based on observations made by the Great Trigonometric Survey. The 8,848 m (29,029 ft) height given is officially recognised by Nepal and China.

And now it seems it is 8850 meters.
2020 - 1856 = 164 years
8850 - 8840 = 10 m
So, medium of present elevation is 1 m / 16.4 years or just less than 61 mm per year, between the 8848 measurement and the present (not recognised by Nepal and China) of 8850 it has been slower, but not as slow as 4 mm per year.
In 4977 years since the Flood, this would add up to: 303.4756 m.
8850 / 303.4756 = a factor of 29.162 times slower than the medium speed of rise.
Square this to get a rough estimate of initial speed ... 850 times the present speed. 51.8555 meters per year.
The medium of the slowing down would then be
850 / 4977 = each year 0.17 times the present speed slower than the year before.
This probably may be not so constantly slowing down evenly, but less slowing down at the start and end, more in the middle. Otherwise the rise would even now be 10 mm less each year.

PS, it seems there may in recent surveys be some height of snow cap involved too, since it's measureable on sighting, as opposed to rock head under it./HGL
