Video Summary

Tony examines his water meter and finds all digits are unique. To determine the water used until the next time all digits differ, he identifies that increasing the smallest digits causes overlap. By incrementing strategically, he sets the digits to 92.013, which keeps them unique. He calculates the water used by subtracting his current reading from this new value, concluding that 0.137 units of water will be used until all digits are different again.
