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. duringthe competition. List any malfunction of equipment. Give any further information which might affect the Tournament Council's assement of the homologation. No Remarks: Towards the end of Sat.22nd April the jump grid was snagged by a skiers long jump skis this required another survey of the jump grid and 40 & 60 meter buoys, this was done prior to jumping on Sat.the 23rd April. The Homologation notice was not posted prior to the start as there were some minor adjustments to be made to the turn buoys, the adjustments were done prior to the start of competition on Friday 21st April but the angles and distances were not confirmed untill the slalom events were completed on that day.

Remarks: I have had my reservations on the timing system for tricks, as there is a delay between when the foot pedals are pressed and the start buzzer sounds. As the time between the beeps is checked when the videos and sheets are reviewed (if a record is thought to have been broken)there were not any problems, it is is only a problem when the last trick is very close to the end of time. This has resulted in the non acceptance of records due to tricks being out of time when checked, during the final scrutinising after the tournament. With the advent of the new trick timing method this will no longer be a problem. End of Document
