The EBS Burn-down chart shows you the adjusted (predicted) hours remaining. Please create a version without EBS.
The menu Schedules > {project} > Burn-down chart (no EBS)
REASON
I am a FogBugz consultant and I spend alot of time putting in new installations for customers. EBS is a difficult concept to put across in the short time I have to do the installation. It also returns useless data until after the first few sprints.
A simple burn-down chart with no EBS would provide a stepping stone to using EBS. It would also demonstrate the superiority of EBS.
