On the Subject of % Grey

But how will you relay this information in between you and the defuser?

This module’s backing will be a shade of grey. The defuser needs to hold down on the backing as the percentage on the module rises from 0%, 10%, 20%, 30% all the way to 100%. You are required to release this module when the backing shade of grey matches the percentage shown on the module.

This percentage shown will not decrease unless you release the module at the wrong percentage. In which case, it will reset back to zero.
