The real issue was that Anning acted too soon.
At that time, in that situation, he decided to distribute the lands impulsively — indeed, on a whim.
Then Napoleon firmly declared that Anning had been contemplating this since 1780, turning this impulsive decision into one that seemed to have been considered for eleven years.
Now everyone believes that this was an action taken after deep deliberation by Anning.
Thus, Anning could no longer change it; he had to push forward, come what may.
Fortunately, in Anning's understanding, someone had already blazed the trail and summarized the experiences, so Anning, relying on his memory, wrote down some of these summaries and distributed them to his subordinates, barely managing to push forward the land distribution.
The distribution of these experience summaries itself became evidence of Anning's careful consideration, reinforcing everyone's belief that this was a long-premeditated act by Anning.
