I'm glad you asked.

Random.org is a True Random Number Generator that I use under certain conditions as a Hi/Low decider to ensure that I don't have any cyclical betting patterns that may turn into a weakness under exposure to a large number of rolls.

I actually SHA-256 hash my seeds and truncate a part of it to fit into the PD3 client seed. Like I said in another thread: OCD about entropy.

Notice the Excel sheet, I keep record of the periodicity of 7+ streak failures to investigate my strategy with a series of value derivations versus the mathematical expectations. The mathematical expected odds of running into a 7+ streak failure given 49.5% odds is about 1 in 119, my strategy in practice after 20,000 rolls is about 1 in 220 currently.

I have a similar 20,000 roll record of PD2 that also reflected this trend (at 1 in 238, exactly 2x). One day when I have met my set BTC quota, I may just share the details my findings with the world...
