Also, one more thing. When Chasriel died, one flower bloomed. The very first flower.

By the time Frisk falls, the entire room is filled with flowers. From just one.

A flower only ever blooms once a year.

So then, how many generations should it take to reach the state that we see it in? This should help give a lower bound to the number of years between Chara's death and Frisk's fall.
