"Changes of engines" is configured to "All 64h"
Generator 1 has 262 maintenance hours remaining
Generator 2 has 298 maintenance hours remaining
The time group for generator 1 is calculated as: 262h/64h = 4.09 = Time
group 4
The time group for generator 2 is calculated as: 298h/64h = 4.66 = Time
group 4
Both generators are in time group 4.
Time group 4 consists of any generator that the time group calculation
total ranges from 4.00 through 4.99.
