Fix the bug where the capacity is incorrectly calculated.

jxguan · web-flow · commit c7e48fc5c4b4 · 2016-07-13T14:21:15.000-07:00
The capacity should be s timed with the number of blocks, instead of added with. Also, the block numbers are zero-based, so a "+1" is needed to get to the correct number.
