I agree that would be a better warning message.
As an aside, we try to separate usage of "sample" and "draw", with a single sample being made up of multiple draws.

Add another message that "warmup is less than the recommended minimum 150 iterations" and then continue to dump a more detailed message that indicates it's just detail.
Summary:
When running Stan programs with low sample sizes (under 300 samples,) Stan returns a (confusing/spurious?) warning regarding the warmup.
Description:
When running an analysis with a sample size under 300, the following warning is generated;
WARNING: The initial buffer, adaptation window, and terminal buffer overflow the total number of warmup iterations. Defaulting to a 15%/75%/10% partition, {List of used valuesfor each}
Reproducible Steps:
In R, run;
Current Output:
Expected Output:
No warning, or perhaps;
Additional Information
This error message occurs even when you specify the number of the buffers and window to rstan;
Current Version:
v2.12.0
