1) Alchera has an atmosphere at about 0.8 the density of earth and an atmosphere made up of methane / ammonia. 20% less resistance perhaps, perhaps less since different gases do have different properties and react differently to heat and resistance. We'll need someone with actual knowhow on how this work to get a "better" picture but I'll use a direct correlative in this case, 0.8 density = 20% less resistance untill we can get a better info yes?
The atmospheric density is crucial, so yes.

2) Alchera's gravity is also about 20% less than that of Earth's so that might throw our known object falling at for xxx amount of time = xxx amount of meter's traveled. (actual speed will vary) Is 20% less gravitational influence enough to "slow" Shepard's speed on re-entry? I do not know, I am not an astro-physicist but again, until we get better or actual info, we could just use the 20% difference as a direct correlation yes?
The Body would bounce off from the atmosphere if it would be much slower, (20000 Km/h was already conservative.) That is independent from the Gravity of the Planet. So no.

3) Surface temperature of Alcheara is -22c, which means that the atmospheric temperature is again in correlation, lower and might again act as yet another buffer in keeping Shepard's body being burned away in re-entry.
Temperature in an atmosphere depends on many different factors. But on the point where the Atmosphere begins it has almost the terms of Space.

4) Shepard may be dead, but he is still fully armored and aside from what seems like a seals breach, is still fully functional. kinetic shields and material meant to withstand EVA work (space absolute temperatures range quite high)
temperatures and variations in space and thus it its conceivable that the armor has some way to keep temperatures on the inside a constant (or at least as best is its able to) near survivable conditions.
an excerpt if you will :
So, (to finally get to the answer!) temperatures vary so much in the absence of air because there is nothing to reflect, absorb, and scatter the entering heat and nothing to hold in the heat on the "night" side. This is why the day/night temperature of the Earth in the northern US during a typical June is 21°C / 11°C (70°F / 52°F), whereas that on the Moon (located at the same distance from the Sun as the Earth but lacking an atmosphere) is 115°C / -180°C (240°F / -290°F).
What all this means is that given all this, are asked to believe that it is possible for a body still encased in armor to re-enter such a planet and not have said body incinerated.
I thought it to be plausible.
True, space absolute temperatures range is quite high, but the entry temperatures of Shepard's body must be approximately 2000 degree Celsius (3632 degree Fahrenheit).
The shields wouldn't withstand the heat for more than a few seconds, and the suite was already cracked and did not provide heat shield capabilities. (how long can you resist a Flamethrower attack in game? 4 - 5 seconds at best.)
And we note even talked about pressure and the fact that the residual oxygen in Shepard's body would be a good oxidant.
imho, under this circumstances, nothing off Shepard's body would reach the ground.

As I mentioned in that other post above (the one with the picture of the Shepard's Xray-ed skeleton, page 815 ) it's not that they are asking us to remove ALL disbelieve, or that there isn't any suspension at all.
In this fictional set piece, applying what is termed the "socratic exercise" if given all the above, given the rules of physics, could this happen? That is science fiction. It asks, what if ... within the realms of reality can something happen.
Lastly, does the above look like I am "spinning" things, considering the use of the socratic exercise in determining whether or not this particular event is plausible?
Of course you are right, and no you don't "spinning" anything, it's just an interesting debate.
