Verifying whether the increased number of corner plots is excessive

Ascertain whether increasing the number of corner plots per paper to offset publication costs using PromoPlot advertisements indeed results in "too many" corner plots, as suggested by some colleagues, by developing clear criteria or evidence to evaluate excessiveness.

Background

The approach may require substantially more corner plots per paper to meaningfully offset fees, provoking concerns about excess. The authors note an unverified claim from colleagues that the recommended increase constitutes "too many".

Providing an evidence-based assessment would inform community norms, editorial acceptance, and practical guidance on adopting PromoPlot without compromising readability or scientific presentation.
