It might. Would be interesting to test.
But if overhaul time is still the same as in VB6, then the time it takes to reduce the maintenance clock is a third of TSO. So if your ships have out for three years, then it would take a year in overhaul to reduce maintenance clock to 0. It can be a long time spent in overhaul, but you might prefer it to keep crew training, which would be reduced when building a new ship.
