I should have paid more careful attention to the pressure bleeder fluid level to make SURE it didn't run out. I did check it from time to time but if I had heard these experiences I would have been paranoid about it, to make dang sure, as I would not have been prepared to bleed them properly. No INPA or anything.
You shouldn't have any problem when only flushing fluid and ensuring the reservoir stays full. Swapping the lines can introduce air into the system. You can mitigate that by depressing the brake pedal so it closes the master cylinder, but somehow I still got air in from the front lines.
