Final answer:
The specific moment when Kino estimates the three men will find them cannot be determined from the provided text snippets, as they do not contain sufficient context.
Step-by-step explanation:
The question appears to inquire about a specific moment in a narrative context, likely from a novel or a story. Due to the lack of contextual information directly related to characters named Kino and the three men he is referring to in the snippets provided, we can't accurately deduce when Kino estimates the 3 men will find them. Detailed context from the actual source material is required to provide a factual answer.
Without the direct text involving Kino's estimation, we can only speculate based on standard narrative techniques that this moment of anticipation would build tension in the plot. The author might have intended to show Kino's strategic thinking or heighten the suspense surrounding the pursuit.
