It is an established fact that only brief moments of overtime are effective.
Chronic long days cause the troops to slow down.
Within two weeks it will take ten hours to do what eight used to do.
In California 12 hour days are 'almost illegal.' That is, you can't compel your troops to work beyond ten hours. California also went after employers using 4 day, 40 hour weeks without paying overtime.

If you can recover their labor waste overtime may be tolerated.
I can't see routine tempos of anything beyond ten-hours.
