As my username suggests , I am a sceptic. Like kav hints I think your "Free Video" is luring the unwary to buy "something".
That aside , your system
Needs a 1,000 bankroll ?
Uses a unit of 10 ? (100 units @10 )
Waits for 20 spins before betting ?
Like kav I look forward to your following posts .Everyone in this forum is interest in claims of " The Holy Grail".
You do now where your nickname derives from, don´t you? Being originally of greek birth, but raised in a northern region of Europe, I still "react" to anything of "greek" origin, especially if it has ancient root.
Diogenes Laertius at IX. 73–74, sums up Scepticism for anyone interested in its true definition quite well which puts anything produced by an open, creative mind, in the Sceptic’s unappreciating and limited ballpark. A Sceptic´s approach t things of any given permutation is a fascinating approach to the unlimited possibilities of a Universe, versus a mind of high, yet still limited knowledge/intelligence in comparison, to say the least.
"The Sceptics, then, were constantly engaged in overthrowing the dogmas of all schools, but enuntiated none themselves; and though they would go so far as to bring forward and expound the dogmas of the others, they themselves laid down nothing definitely, not even the laying down of nothing saying, for instance, “We determine nothing,” since otherwise they would have been betrayed into determining; but we put forward, say they, all the theories for the purpose of indicating our unprecipitate attitude, precisely as we might have done if we had actually assented to them."
When it comes to the bankroll of 1000 Euros contra the unit-size of 10 Euros, yes the system is suffciently played with that 10:1 factor, in terms of money/betting management. At least in my case.
You could as easily play it with 100 euros with 1 euro units, on a low limits table and work yourself up to a larger bankroll.
Personally, I find 1000 - 3000 euros a nice and sufficient bankroll to risk, when I choose to enjoy the game, knowing my return will land in the near ballpark of 30-40% after a days play (which includes 1-3 sessions, depending on the number/pattern appearances during 40-80 spins in each entered session).
If I play more than that, something, what i call (in a coming post) "psychological/enviromenatal" interference starts to affect the system, increasing the risk of a losing session occuring before the end of the day.
