Correct. I edited the schematic.That won't work well as you have the second 555 trying to brute-force pull the first 555 output low, when it is high.
Correct, but in my opinion it would be quicker and definitely more precise then adjusting potentiometers.Of course, I can use an mcu, but if I give up this method for now, is there another way?
For example, if 8 seconds is increased to 10 seconds, I have to compile and program mcu again.
