16.3 The Finishing Window is the time for boats to finish after the first boat sails the course and finishes. Boats failing to finish within the Finishing Window, and not subsequently retiring, penalized or given redress, will be scored Time Limit Expired (TLE) without a hearing. A boat scored TLE shall be scored points for the finishing place [one][two] more than the points scored by the last boat that finished within the Finishing Window. This changes RRS 35, A5.1, A5.2 and A10.
A TLE score is based on the number of boats that finished and with the new rules the finish definition includes the requirement of starting. A UFD boat that meets the requirements of finishing increases the TLE race score, but a boat that was UFD and OCS doesn't.
The above sailing instruction will force the race committee to maintain two versions for letter scores like BFD, UFD, DSQ, RDG, RET and DNE. eg. You can have a UFD score for a boat that meets the definition of finish and start and a version that doesn't meet the definition of start or finish. The first one affects the TLE points for that race, but the second one doesn't.
It looks like that a simple TLE score could cause a lot more work for the signal and finish boat crews.
