Second pass at: The storage lookup and where its data comes from posts 31–43

Tools that run entirely in the browser send nothing anywhere, which matters more to some people here than others and is worth stating either way.

Seconded. It reads as careful rather than confident, which is the right register.

Everything in post #29 holds. The case it does not cover is the one I have.

I think the storage lookup question is answerable and has not been answered, which is a more optimistic position than most of this thread.

Narrowing post #33, because the general version has more than one answer.

Adding a null result on storage lookup. I looked, carefully, and found nothing, and null results deserve posting precisely because they never are.

Worth separating two things that post #33 runs together.

Precision and significant figures: the calculators do not round to match your input precision. If you input values to one decimal place, the output might have more. Use significant figures appropriate to your input precision.

Correct me on the arithmetic if it is wrong; I would rather know.

What I can speak to on storage lookup is narrow, so I will keep it narrow rather than generalising from it. Beyond that boundary I do not know.

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.

None of the above is medical advice and I am not qualified to give any.

Post #37 answers the question as asked. The question underneath it is different.

Distinguishing three things in the storage lookup discussion that keep getting used interchangeably: the observation, the proposed mechanism, and the recommendation that gets attached to both.

Understood. Thank you for being specific about the limits of it.

Post #37 is the version of this I will quote in future. One addition.

I would rather this thread reach "we do not know" about storage lookup than reach a confident answer that nobody can support when asked.

Building on post #38 rather than restating it.

A calculator that shows its working is worth ten that give an answer. The whole value is being able to see which step you disagree with.

Post #40 put the caveat in the right place and I want to underline it.

Rounding behaviour is where two tools disagree. One rounding to the nearest graduation and one to two decimal places will produce different advice from identical inputs.

Happy to expand any of that if it is the useful part.

I keep a log for storage lookup specifically because my memory of it turned out to be systematically wrong in one direction. Six weeks of notes cost nothing and settled it.
