This question depends on how high you set the radius. But the math works such, that for people as ranked between 0 and 100%, about every 15% your amount of matches doubles, at the top and bottom 10% that math doesn't work out anymore tho, it goes even worse than exponential.

The difference between the top and the bottom is about 2 orders of magnitude

Incidentally, the difference between the average male normie and the average female is 4 orders of magnitude. That's how far the SMV of females is apart.
