What data format should I paste?

Paste one temperature and mass pair per line, such as 25, 12.50. Temperatures should increase down the list.

How is step loss calculated?

Each step compares the previous checkpoint mass to the current checkpoint mass and expresses the change as percent of initial mass.

Can the calculator handle mass gain?

Yes. Negative step losses are shown as mass gain and trigger a note to review buoyancy correction or oxidation assumptions.
