Population (as best known before the Breakaway)

In the Breakaway episode, there are a number of population changes leading up to just before the actual Breakaway event.

The two pilots and stewardess that brought Koenig to Alpha. Did they linger only long enough to take Gorski (first entry under Losses below) to Earth?
Collins (first name unknown -- not Eddie Collins): an Eagle pilot who grew symptomatic after Koenig's arrival and before Breakaway. His fate is not mentioned in the episode. He may have died before Breakaway, died of his illness after Breakaway, or perhaps (unlikely) recovered.

Cmdr. Gorski: Though we don't actually see him leaving the base, there are 3-4 days between Cmdr. Koenig's arrival at 23:35 Lunar Time 1999/09/09, and Breakaway some time during 1999/09/13, and the character, unlike Comm. Simmonds, is never mentioned again. The Editor believes it is almost certain Gorski leaves the base.
Nine who died prior to Koenig's arrival, including Jim Nordstrom shortly before on 1999/09/09.
Frank Warren: already in Medical Center, dying, when Koenig first sees him. Dies at 13:28 (day unclear to Editor, but before the Breakaway event).
Eric Sparkman: also already dying. There are no signs of brain activity or, beyond machine support, cell life, and after consideration, Helena stops life support, and he dies. This too happens before the Breakaway.

Again, this counts changes leading up to, but not at or after, the Breakaway event.
It is possible there were other arrivals or departures (Eagle flights between Earth and Moon or between Alpha or the space station in lunar orbit), which cannot be accounted for. The Conclusions below are thus that much less certain.

02 Gains: Koenig and Simmonds
12 Losses, inc.: Gorski (returned to Earth), Frank Warren, and Eric Sparkman
04 unknown (3 probably not a factor, 1 perhaps a death but still unknown if/when)
With the 311 figure cited by Earth just after Breakaway (see Population at the Breakaway), if the visual evidence is complete, Alpha's population just before Koenig's arrival (at 1999/09/09 ETA 23:35) is perhaps 313 (313+Koenig-Gorski-Warren-Sparkman = 311). Alpha's population even earlier, before the nine who died prior to Koenig's arrival, is perhaps 322 (322-9 = the 313 just above).
