Question about the vaults

[VikVega]

According to the timeline on the Fallout wiki, before the bombs dropped, Vault Tec had commenced several drills around areas where vaults were built. This, in turn, had a "cry wolf" effect on subsequent drills, with less and less people showing up for each drill. My question pertains to vaults such as: Vault 43, Vault 68, Vault 69, Vault 77, and Vault 27. Each of these vaults required a certain amount of population per each Vault in order to follow experiment protocol. If less and less people showed up per drill, how did Vault Tec assure that everyone who was scheduled to make it into said vaults did so successfully?
Vault 43 needed 20 men, 10 women, and 1 panther.
Vault 68 needed 999 men and 1 woman.
Vault 69 needed 999 women and 1 man.
Vault 77 needed at least one man to enter, but if said man chose to ignore the drills the day of the bombings, the vault would be rendered useless.
Vault 27 needed to be purposefully overpopulated.
And for that matter, how did Vault Tec expect to get a panther into the vault on the day of the bombings on such a short notice?
Maybe I'm overthinking a video game way too much, but any help would be appreciated.

The easiest (and most probable) answer is that those were all ballpark figures. You never hear from a post-war authority in a position to know whether those population goals were actually met.

Regarding whether they were actually met, though, it's likely that the "cry wolf" effect wasn't seen as a problem mainly because the Vaults were (to borrow the line from Penny Arcade) never meant to save anyone. In cases where the experiment absolutely required certain occupancy numbers or tighter admission controls, I'm sure they had means in place to ensure that the proper people showed up, though what those might have been is anyone's guess. It's possible some of those vaults took a page from Vault 112's book and closed early, too.

As to the panther, they probably already had it on site

60% of the time it works every time.

In terms of getting all the people necessary to load up a vault; I'd think they'd be able to get it figured out. Since there were waiting lists and a lot of people didn't get in.
