If you're figuring just what your team can accomplish in 2:15 minutes, you can break it down to points vs time.
For every tote you have 2pts
For every tote with a bin on top you get 6pts (This works across the board. If you get 6 bins, you could stack 6 single level totes with a bin on top for 36pts. Or a 6 level tote stack with bin for 36pts)
Now a sample equation can be:
135s = T +
Never mind I just put it into a spreadsheet to make it easier. I gave everyone "edit" access, so play with it or make a copy.
