 +===Discrete Conversion Notes===
 +
 +If using Calculate to convert data from analogue to discrete, you might experience 'drift' in the exact times when your state transitions occur. If requesting data at 5s resolution, your on/off times might drift by as much as 10s. 
 +
 +If you need to capture very accurate on/off times for utilisation purposes, we suggest performing this calculation in your backend, or using **ModelHost**.
