Each item of PHP 2D array $g contains
- ID in index 0,
- delay in index 5,
- binary in index 6,
- category in index 7,
- weight in index 8
For each ID show cat for binary 1 having highest delay along with weight and category for binary 0 having highest delay along with weight.
If multiple categories have delay within 60 between each other, chose the one where weight for binary 0 and 1 for the same category and delay are closest to each other. The categories shown for 0 and 1 must be the same.

The code below works well for highest delay, but for lowest returns the same. How should I modify the code to work correctly for lowest as well? E. g. for the ID 18572 the output should be Lowest Delay: cat: 44, Outcome 0: 184, Outcome 1: 199, Delay: 14
