Hi Jon;

bumpsize 100000		# minimum savings (threshold) to bump level 1 -> 2
bumpdays 1		# minimum days at each level
bumpmult 1.25		# threshold = bumpsize * bumpmult^(level-1)

I've never fully analyzed that to see what it really does, so those 
figures, which haven't changed in at least a decade, originally came 
from a SWAG.

Point being that anytime I see a planner line that says its to days-1, it 
always does a level 0 on that DLE.  Most are small enough to be a never 
mind when the average total is north of 20G's anyway.
