[...] if ISS ends in 2020.

Wandering a bit further afield, have you heard if the simulations show any
difference in how much debris will reach the earth for a whole-ISS entry
interface vs individual modules entering seperately?

I understand that "picking one's spot" argues for diving in as a single
unit, although a cheap re-entry "tug" device could assist with control in
the IMES scenario.
