Dialog description

Select a method for calculation of CCTV survey Structural peak score and Service peak score:

Calculate Peak Score at 1m intervals: the pipe is broken into discrete lengths of 1m. The structural/service score is calculated for each 1m length and the maximum of these values taken to be the peak score.
Calculate Peak Score at 0.1m intervals: the structural/service score is calculated for 1m lengths of pipe on a rolling basis using 0.1m increments to determine the start of each metre length. The maximum of these values is taken to be the peak score.

Select a method for calculation of CCTV survey Structural mean score and Service mean score:

Calculate Mean score using surveyed length: CCTV survey Structural/Service mean score is calculated as Structural/Service total score divided by survey length.
Calculate Mean Score using total pipe length: CCTV survey Structural/Service mean score is calculated as Structural/Service total score divided by Total length.
