Aww, thanks. ^^
Lol, well, one fun way I like to measure Generation X's run is by the number of holiday issues. It's been a while since I read it, but if you're going through it now, I'm pretty sure they had at least two, maybe even three Christmases over the course of Gen X Vol. 1.
So, judging by that alone (and assuming they don't live in a world with multiple Christmases per year), plus the fact that some time had passed since Gen X at that point, it's legit for Chamber to say to Jubilee "over the years." They never like to specify how many years for just this reason... the problem with the ages.
If it was three Christmases, that explains 13 to 16 for Jubilee. ;D
Their ages at the beginning of Generation X were established in the Collector's Preview... I think it was something like 13 and a half for Jubilee and "a very hard 14" for Penance... 16 for Monet...
Back in 2015, I posted this:

Since then, I've actually bought that Collector's Preview, so I can check, but I'd rather not go digging for it, lol. I think of note is the fact that we were thinking about two years had passed in the Marvel Universe the ten real years since Gen X came out in 1994. If you apply that (albeit flimsy) logic that two years in Marvel time is equal to ten years of real life time, it's been 5 or maybe 5 and a half years since Generation X began. Which is of course hilarious because in real life, we've moved waaaaaay past the '90s. But, eh, sliding time scale.
That's great that you're basically finished with the recommended reading list.
It's probably a silly question, but you have Chamber's miniseries on the list, right? I forget exactly when it happened, but it was after Generation X ended...
