Data Interpolation

</h1>

One of the unique features of Performance Manager is its ability to interpolate data when statistical 
polling results are missing or delayed. Other performance tools may store the missing data point as zero, 
but this can distort historical trending. Performance Manager interpolates the missing data point by 
comparing the data point that preceded the missing data and the data point stored in the polling interval 
after the missing data. This maintains the continuity of the performance information.
