Awards

All trophies are to be provided by the Porsche Club Great Britain.

Per round, trophies will be issued to 1st, 2nd, and 3rd in each class subject to number of starters - 1st place, 2 starters, less than 6 starters in class trophies to 1st and 2nd, 6 or more starters in class trophies to 1st, 2nd and 3rd or in a manner equal to that adopted by the event organising club.

Championship overall, trophies will be issued to 1st, 2nd, and 3rd overall and 1st, 2nd, and 3rd in each class subject to 6 registrations for class, less than 6 registrations, awards to 1st and 2nd only. There will be an additional trophy for the best placed lady. Trophies will be at the discretion of the organisers.

Points scoring system

Championship points will be awarded on the basis of 20 points for the fastest finisher in the class where there are 3 cars or more competing. Points for positions two, three, four, etc. will be determined by the time gap between their fastest time and that of the class winner. Where less than three cars are competing, maximum points will be 19, less than 2 cars maximum will be 18.

Example: Where the second placed competitor records a time 0.5 seconds slower than the class winner, second placed points will be 20 - 0.5 = 19.5 points. If the next competitor's time is a further 0.6 second slower, points for third place would be 20 - 1.1 = 18.9 points. Example based on more than three competing cars in the class.

In addition, each competitor will receive at each round a bonus equal to 1% of the time gap between their fastest recorded time in competition and that of the next slowest competitor. This bonus will be rounded to three decimal places. For example, if the fastest competitor has a winning margin of 0.3 seconds over the next fastest competitor, the bonus achieved by the class winner would be 1% of 0.3 = 0.003 points. Where the second placed competitor has a margin over the third placed competitor of 0.45 seconds a bonus of 0.005 points (1% of 0.45 = 0.0045, rounded to three decimal places = 0.005) would apply. This bonus will apply irrespective of the number of competing cars in each class.

A competitor's best eight scores will count towards final Championship points / positions. Save that the best eight scores must include a minimum of two sprint or two hillclimb events, even if this means the discarding of higher points scored, e.g. a competitor's best eight scores cannot consist entirely of hillclimbs. This will not apply if less than eight scores are counting.
