Are 15 citations few or many?
Relative metrics may help.
YCR = Year / Citations / Relative
Relative > 1 is good; more is better.
Relative 0.80-0.99 is good enough.

Scientific articles differ widely in quality and influence. To reveal those differences, we are building a concise suite of performance metrics, first tuned for Oncology and now extended to the broader Biomedical literature. As a non-profit scientometrics initiative focused on relative citation measures, we aim to offer transparent, field-sensitive indicators for researchers worldwide.
