Nobody has said the unglamorous part of calculator yet, so: most of the variation is explained by things that are boring to write about and easy to check.
A calculator that gives a right answer to the wrong question — does this still hold?
Where I part company with post #5, and it is a narrow parting.
Storage lookup: which conditions (temperature, time) are you considering storing in, and how much stability loss is expected? The calculator gives a rough estimate based on typical stability data. Not a substitute for your compound's specific stability data.
Caveat: everything above assumes the paperwork is what it says it is.
Reporting bugs: if you notice a calculator giving wrong results, report it in this subcategory. Bugs are fixed when identified.
On post #16 — agreed on the reasoning, with one qualification.
Where a calculator and your own arithmetic disagree, the productive move is to find which step differs rather than to decide which is right.
The residual-volume question belongs in the tool rather than in a footnote, because it is the difference between the calculation and reality.
The literature is thinner on this than the confidence in the thread implies.
