Insignificant for a single particle, but compounded for increasing mass. Because the bias slows the rate of decrease of gravity with distance AND progressively intensifies over increasing distances from the source of the gravity, the effect would be to progressively load the deficit at the tail end gravity furthest from the source. As this effect intensifies, the bias nearer the source loses the effect entirely. But because the original slight bias does exist, and because it progressively intensifies further from the source, and because that means the deficit is progressively pushed further toward the tail end (because the bias intensifies further out), there will come a point, where the rate at which gravity lessens is increasing faster than predicted beyond a certain line. And because the thesis is for a slight bias that actually slows the rate down, the fact this corresponds to an increased rate of descrease after a point, is progressively exacberated by an increased bias for slowing the other side of the point given there is now less tension the other way due to gravity falling away more steeply the other side of the line. So the progressive effect would be that gravity levels off more than predicted right out at the edge of the galaxy, and what had been a smooth decrease in its effect, transforms into a steepening gradient over a shorter distance. All which would create not only the dark matter effect, but also the observed symmetries of the effect, in relation to the clumps of denser ordinary matter in the galaxy. It depends on one tiny effect. It makes predictions that feasibly could be checked. It doesn't have the problems of the other gravity solutions. It doesn't need a 'cause' for the bias, because that's the conjecture part. 'course speculative, but you're rather a cheeky bugger to be protesting of that :o) I think you should at least be willing to make the effort to understand so simple an idea.
