Your concerns are noted and appreciated.
I have been doing this schedule for over 10 years and have mitigation strategies in place. The problem is that I do not always use them.
I considered quite a while before going live with this, but if you look at what was posted, I think you will see that there is also a problem in recognizing microsleep events when they occur.
I posted what I did to point out that there is a method for a person, properly forewarned, to recognize that they themselves have experienced a microsleep event.
The loss of the situational awareness/ confusion that results from a microsleep event is a useful warning of a microsleep event. One only has to recognize what it means.
Considering that aircrews are reporting microsleep events while flying makes this an appropriate forum for such a discussion.
