What teams have improved the most in the shortest amount of time?

[GKrotkov]

This won't exactly be news to the OP, but I'd like to throw 1257's hat into the ring for all those who don't know.

2016 Season:
- Captained the winning Mt. Olive District alliance.
- #1 seed and Finalist at Bridgewater-Raritan District
- Won MAR Champs.
- Archimedes Semifinalists (5 points from finalists)
- Qualified for IRI

2015 Season:
- Captain, quarterfinalist at Mt. Olive
- 2nd pick, finalist at North Brunswick
- Unselected at MAR Champs

Of course, this doesn't tell the whole story*: they had an interesting 2014 season, with the #2 seed at MARCMP and a win as a 2nd pick at Clifton. But for reference, they went unselected entirely in the 2013 season. I still argue that 1257's rise has been meteoric.

*Well, heck, seeing as I'm not on 1257 I can't tell the entire story.
