^I know all that, but it's still strange that they decided to assign more weight to TFF's date than TWOK's. After all, it was a Romulan who said "twenty years," and Romulan years (or Nimbus years) could be shorter -- or she could've been rounding up. But Kirk and Khan, two Earth natives, both independently said "fifteen years" in TWOK, without ever hearing each other say it. Of the two, that's the one more likely to be accurate. So it's strange that they went the other way, especially since TFF is such a poorly regarded film, even considered apocryphal by some.
