[ NOT APPLICABLE -- SECTION DELETED ] END OF HOMOLOGATION FORM It is important to leave the above section in the exact format as it will be processed automatically. The following section is where free form comments are added and attachments are made. HOMOLOGATOR'S REMARKS Give details of any variations of IWSF rules. List any alterations to the course, etc. during the competition. List any malfunction of equipment. Give any further information which might affect the Tournament Council's assement of the homologation. No rules variations. Used Corson Trick Timer program 02D -- encountered some difficulties with USB capture device and had to try different frame rates, then discovered issues with program and handling of some clips at one frame rate and others at a different rate. Got that all sorted out and obtained correct accurate official results. Used 3 trick judges working from wireless video fed from the boat, through a two stage wireless link into an inside office at the end of the lake. Used a special mirror arrangement on the camera which provided side views off to the left and right sides of the boat, presented above and below the main center image which was from directly behind the boat. Did not have any tricks performed way outside the wake, but this arrangement would have covered these, had they occurred.
