As a veteran of the industry in the UK, having worked on a number of similar budget films, I can tell you categorically that these figures are entirely fabricated.
On a film like this, the A and B camera would be paid approximately the same amount. Camera Operator (regardless of A or B cam) would be the highest earner in the department, other than the cinematographer. So there is no way that the A camera 2nd Assistant gets more than the B cam operator. Having done this job myself, I can tell you that's a fact. I suspect a number of the other figures are also made up. Misleading, unhelpful, should check their facts before spouting this inflammatory nonsense.
