Well I am glad to see that I'm not the only one that enjoys this thread (in a kind of sadistic way).
You make the observations I often think about.
The abuse I get here is non-stop and rather than bristle at the attacks and accusations, theories and hysterical comments as I would have once upon a time, I almost revel in this acidity nowadays.
The reality lies somewhere in between what Mr. Grafmann projects and losing - this year I am up a good amount but nothing like Grafmann states.
As for the shite aspect - let me refer you to this post I made concerning 13 consecutive bust deposits at one site with NO bonus!
Yep. My 13 consecutive deposits at Jackpot Joy without a feature or w/d were against the maths. 100 spins a time balance. My 6-week winning run at Casumo I had, making nearly 15k euros was against the maths. Getting 5 consecutive features at Betfred of over 100x, including a 700x and 1500-odd x were something I have never got close to since. Going over 2300 spins without a feature was too. Once going 73 L's before getting a 17x feature on the 74th. was another I remember. The bulk of my recovery in the last 10 months or so has been based on doubling a deposit then raising stakes and...
And the other side, for a small 50 quid in:
3628x bet Bonanza, at the rogue Freaky Vegas casino, before it went tits-up a few days later.
I won 12k euros at Casumo over 3 weeks, almost every session won, 1-2 euro bets on Bonanza. Sky Vegas, lost over 13k in my time playing Bonanza there.
Over 10 years I am down a decent 5-figure sum on the bastard game, which is quite reasonable considering the hundreds of thousands I have turned over playing it, possibly a million or two.
I play a 96% Nextgen version last time I looked. This conspiracy nonsense people spout about the game being changed mathematically always makes me laugh. The RTP versions of 96/94/91.21 are independently audited. The huge majority of version code changes have fuck-all to do with any game characteristics, but are things like stake limit changes (UK), display, stake increments or performance updates. As well as that, you have spin speeds, sounds and imagery.
But never, ever let facts get in the way of cognitive bias and paranoia born of losing, which we all do over time.
