Preparation overage
See it
Preparation overage is an intentional extra amount added to compensate for practical losses such as transfer residue. If the base volume is 840 mL and the selected overage is 5%, the planned volume is 882 mL.
Understand it
Overage is a planning choice, not a biological requirement.
Show base volume and overage separately.
Record the selected percentage so the calculation is reproducible.
Important boundary
Do not hide overage inside a rounded final number.
Try it
Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
