is there Air Resistance in AR?

Initially I thought that there wasn't any air resistance in Armadillo Run, and that the 'cloth parachute' efect was caused by some other weird physics. But I was talking to someone else who seemed pretty sure it was a simulation of Air resistance.
So I tried it out (see attached file):
The results I got show that there is a really basic air resistance - different materials fall faster or slower than others. But it isn't based on surface area/etc or anything else which might affect air resiustance in real life - it is just based on the different materials. The order of falling acceleration is below:
Armadillo (fastest)
Rubber
Metal Bar
Metal Plate
- big gap -
Elastic
Rope
Cloth (slowest)
Why does a horizontal metal plate fall faster than a piece of rope?
There is one other air-resistance like effect, which sees the endpoints of cloth objects bending down (although I think the overall centre of gravity stays the same)
Anyway, I'm sure many of you have tried a similar thing, but even if you haven't, what are your thoughts? is it 'air resistance' or some other phenomenon?
