She wasn't in Cryo.

[quote=@AdamantiumWolf]she's only been out of the vault for a year, it's highly unlikely she would have accomplished all that[/quote]

She hasn't accomplished everything you're saying.

She ignored everything else that was not standing in the way between her and her father, finding him rather quickly. I would guess a couple weeks at max. From then, she traveled with him for a few days before losing him again. Somewhere during her hunt, she would have destroyed Megaton because the people there were stupid enough to worship a live nuke. That would be about 3 weeks.

Since it was the Enclave that had caused his death, she partnered up with the Brotherhood. After seeing their big robot, she asked how many they had. They did only have 1 so she told them to begin construction on another 1 and she led the charge with the first one to the first big enclave base in the Capitol Wasteland. As she thought, the first one had been destroyed, but it had done a good job of making a big enough hole in the wall for her to get in and start killing people. She returned to the Brotherhood sanctuary but the second robot wasn't ready so she took some power armor training and went to the next Enclave base with a handful of Brotherhood stealthers. They killed everyone in this base with their stealth, a few of them having to use stealth-boys. By the time they got back to the Brotherhood base, the second robot was ready for the big attack on the third big Enclave base in the Capitol Wasteland. However, because they took the first one down, they knew how to take it down again, so she used it as a distraction to sneak in the back and kill everyone inside while everyone outside was fighting. That would take about 3 months.

After that, she began wandering. She Paradise Falls, bought a slave to carry her things, and went back to wandering. This could take as long as 6 months or as little as 6 days.

In her timeline, it has been less than a year, she used the leader of a band of raiders as a hostage to get the female raiders in the group to join her before killing the leader. She has just now started collecting them for her army. She hasn't gotten more than 4. That would take a couple days at most.
