That's really all just a lot of information to prove that I am just that unlucky.
Afraid this is about the only thing you said that's useful. Not to be nasty, but while it seems like you should get your stuff on the third RE, it doesn't work like that.
Your first RE has an 0.2 chance of success. Your second also has an 0.2 chance of success. The chance of both succeeding is 0.2*0.2 which is 0.04. Your chance of at least one succeeding is 0.2+0.2*0.8, 0.36. The chances of both failing are an inverse on the maths, 0.8-0.8*0.2 = 0.64.
Your chances of success will never get any better, there is no streakbreaker. It should be more likely to get at least one as time goes on, but there will be outliers. Probably one of the bigger flaws off the system.
