Progress – When should I go from 100% to 0%, or vice versa?

I have a web app I'm building for my business which essentially tracks an employee's progress doing a pick in a warehouse.

The interface has a progress bar that's colored in, and it's full, and as the user picks the progress bar depletes, from 100% down to 0% -- once it reaches 0% the info no longer appears on screen.

However it might be more intuitive for the progress go from 0% picked to 100% picked -- but I feel like a pick being deleted after reaching 0 is more intuitive than being deleted after reaching 100.

I feel like either way I design it, it will be quickly understood by the people who use it, but if one is slightly more intuitive than another I'd want to take that into consideration.
