If you integerize True Counts in different manners, the frequencies of those true counts will change. This chart provides the frequencies for the three methods of integerization: flooring, truncating, and rounding. These are defined on the second page in the section on true count calculation starting at page 95.

The green and red lines (flooring and truncation) are identical for counts of +1 and higher. The red line indicates a very large percentage (42%) of counts of zero for truncation. This is because all counts between -.999 and .999 will truncate to zero. Truncation is a bit inferior due to this large peak at TC zero. When you have so many hands all identified as a count of zero, the count is less precise and an index of zero less valuable. However, the overall effect on advantage is not high.
