Cumulative distribution of normalized number of shares per block
The chart shows the cumulative distribution function for the probability that a block will be found after a given number of contributed shares. The horizontal axis shows the number of shares divided by the current difficulty (i.e. normalized shares), the curve shows the proportion of blocks found after less than the given number of normalized shares.
For example, the theoretical curve shows that 87% of blocks should be found after less than (2 * the current difficulty) shares.
