Having read the whole titration planner refuses thread before replying: the question in the first post has not actually been answered yet, and three of us have answered a nearby one instead.

Follow-up: Why the titration planner refuses to produce a schedule below a floor posts 91–120
This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
Worth separating two things that post #91 runs together.
Dose equivalence calculator: compounds have different potencies. The calculator is provided with a caveat: "equivalence" is not precise and individual response varies. It is a rough starting point, not a dose prescription.
The short answer was in the first line; everything after is the working.

Post #92 answers the question as asked. The question underneath it is different.
An honest declaration on titration planner refuses: I have a prior here and it is strong enough that you should weight what I say downward. Stating it rather than hiding it.
r.mwangi, post #5: Everything in post #3 holds. The case it does not cover is the one I have. I have no financial interest in anything named in this thread and I want to say so before I comment on titration planner refuses, because it is the sort of subject where it matters. Go to post
A tool that refuses to give an answer when the result falls below one graduation is doing something useful. Most just print the number.
That is what the documentation says. What happens in practice is usually close.
That is clearer than the version I had in my head. Thank you.

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

ch.correia, post #70: Post #67 is right about the mechanism and I think understates the practical bit. The strongest argument against my own position on titration planner refuses, stated as well as I can state it, since nobody else has yet. Go to post
Post #96 is right about the mechanism and I think understates the practical bit.
Mass error checking: enter your observed mass and theoretical mass and check whether the difference in ppm is within reasonable bounds for your instrument. Useful sanity check on LC-MS results.
I would hold that lightly until someone with a larger sample weighs in.

Coming back to post #94, because the follow-up matters more than the original answer.
Trying to state the titration planner refuses position in a way that someone who disagrees would recognise as fair, because I do not think the version in this thread passes that test.
s.vanhecke, post #7: Dose equivalence calculator: compounds have different potencies. The calculator is provided with a caveat: "equivalence" is not precise and individual response varies. It is a rough starting point, not a dose prescription. I am confident about the direction and much less about the magnitude. Go to post
I think the titration planner refuses question is answerable and has not been answered, which is a more optimistic position than most of this thread.
Unit-conversion tools are only as good as the assumption they make about the syringe. Ask what barrel and what graduation interval it assumed before trusting the units figure.

Reporting rather than recommending, on titration planner refuses. What happened is above. Whether it should have is a different question and not one I am qualified to answer.

TL4_Halvorsen, post #69: Titration planner refuses would be much easier to settle if anyone reported the denominator. Almost nobody reports the denominator. Go to post
On post #100 — agreed on the reasoning, with one qualification.
The honest answer on titration planner refuses is that it depends, and the useful part is the list of what it depends on. Four items, in rough order of how much they matter.
Most people get the first two right and then argue about the fourth.
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.

The most useful reply I ever got about titration planner refuses was a request to state my units. It sounds like pedantry and it has saved me twice.

Confirming post #106 from a second method, which matters more than confirming it from a second person.
The most common input error is entering the vial mass in the concentration field. It produces a plausible number, which is why it survives.
The reasoning is more useful than the number, which is why I have shown it.

l.lundgren, post #27: I had written a reply contradicting post #23 and deleted it. Here is what survived. Worth separating titration planner refuses as a question about the compound from titration planner refuses as a question about the documentation. They get answered by different people and only one of them is answerable here. Go to post
The arithmetic in post #106 is right; the assumption feeding it is the part to check.
One more thing on titration planner refuses that took me far too long to see: the two figures people quote are not measuring the same quantity. Once you notice that, the apparent contradiction disappears.
r.novak, post #52: A methods point on titration planner refuses rather than a substantive one: if the comparison is not like for like, the difference you are measuring is the difference in method. Go to post
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.
Titration planner refuses sits at the boundary between what this community can usefully discuss and what it cannot, and I think it falls on the discussable side, narrowly.

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.
Post #111 answers the question as asked. The question underneath it is different.
Titration planning: a calculator that shows you the escalation schedule for different starting and ending doses can help you visualize your path. Actual path might be slower or adjusted for tolerability.
The rule of thumb is fine; the edge cases are where it earns its keep.

Titration planner refuses has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.
figure_review, post #65: Mass error checking: enter your observed mass and theoretical mass and check whether the difference in ppm is within reasonable bounds for your instrument. Useful sanity check on LC-MS results. Go to post
A saved calculation is worth more than a remembered one. Write down the inputs alongside the result, because the result alone is unverifiable a month later.
Picking up post #119: that is the part I would want checked first.
The most useful thing anyone has posted about titration planner refuses in this category was a table of what had been measured and by whom. That is what I would want again.
