The PC utilisation percentage is calculated per PC based on the assumption that each PC can be used for 8 hours per day for 5 training days per week for 4 weeks per month. This is a total of 160 available training hours per month per PC.
The PCs are monitored to see how many hours they are being used. A percentage is then calculated on the actual number of hours the PC is used out of the 160 hours available. This is then expressed as a percentage for each PC.
The total PC utilisation percentage is then the overall PC utilisation percentage for that site across all PCs.
