If round ratings were actually normally distributed around a player's mean, a ratings difference of 67 points from one round to the next would happen about one in 10 times, with bigger differences as follows:
67 point difference, 1 in 10
105 point difference, 1 in 100
134 point difference, 1 in 1,000
159 point difference, 1 in 10,000
180 point difference, 1 in 100,000
200 point difference, 1 in 1,000,000
217 point difference, 1 in 10,000,000
234 point difference, 1 in 100,000,000
67 point difference, 1 in 10
105 point difference, 1 in 100
134 point difference, 1 in 1,000
159 point difference, 1 in 10,000
