Something interesting I noticed this week with the 4/6 slots at 16:00
We've had loadshedding 13:00-15:00 on stage 4 this week and on stage 6 it would have been 13:00-17:00 on some days, so the power goes out from 13:00-15:00 and then again from 16:00- 17:00
So, instead of the neighbours turning off their generators at ~15:10 and back on at 16:00, they just keep running for the full 4 hours. 2 houses in the street does this.
I'm curious why they don't save some petrol, but I guess it's easier to just run the full ~4 hours and be done with it.
