I don't even see why them roughly representing time is a problem due to them raising in a fibonacci sequence.

If they were a day each, it's not like the jump from 5 to 8 means it's going to take 3 more days, but that it's gotten more complex and maybe it'll still be 5 or 6 days but I can't be sure because this one has a lot more unknowns that might not reveal themselves until I'm into it. That's why we're forced to go from 5 to 8 and not a 6 or 7.

The uncertainty is built right into it, so it can't be exact time, but at the same time trying to ignore that they're still time related is stupid.
