This poll has to do ONLY with Singer's SPS (and other system) claims. There is a separate poll for his double up claim.
So Singer claims to have made amended 375k over 4 years playing a video poker using progressive wagering system, using stop limits and "special" (less optimal plays) overcoming negative expectation, all of which go against accepted mathematical principals.
Do you find this claim credible? Again, I am going to ask that people set aside any personal feeling they may have about Rob.
