This was not merely because Arthur acknowledged the accuracy of the experimental data, but more because Arthur actually wrote the word "resistance."
It should be noted that, the reason why he was widely criticized during the "calculation of current" was because he proposed this new concept of "resistance."
In this era, electricity was still an emerging field, with many fundamental concepts yet to be fully established. Additionally, since most researchers lacked sufficiently precise experimental apparatus to measure the relationships between voltage, current, and resistance, the concept of resistance was not widely accepted in the scientific community, nor was it as well-defined as it would be in later times.
However, as the second leading figure in Britain's electromagnetism and one of the academic authorities in electromagnetism in Europe, Sir Arthur Hastings dared to write the word "resistance," which was enough to indicate his stance.
