S10 ANNEX 4 3.C6
PRECISION CIRCUIT IN THE SHORTEST TIME (‘Clover leaf slalom’)
tpen: = t_pil + m * v_pen
Q: = LOG(3 * t_best / (t_pen – t_best + 3))
tpil = the measured pilots time (seconds)
m = the number of missed targets
vpen = the time penalty for each missed target (seconds)
tpen = the pilots time (after penalties for missed targets)
tbest = the best time (after penalties for missed targets)
Q = the task value before normalization
Note: Spreadsheet formulas:
tpen: = _t_pil + m * v_pen_
Q: = LOG(3 * t_best / (t_pen – t_best – 1))
And same in S10 A4 3.C7, S10 A4 3.C8, S10 A4 3.C10, S10 A4 3.C11
Section 10, 4.29.3 states that
"Tasks shall, as far as practicable, conform to the following guidelines in standard championships:
For Paramotor aircraft classes PF and PL:
A) Navigation: 33% of the total value of the tasks flown.
B) Economy: 33% of the total value of the tasks flown.
C) Precision: 33% of the total value of the tasks flown."
This rule is correctly in place to ensure complete fairness to all pilots, and to encourage pilots to develop their skills in all types of task rather than to specialise in slalom. Those who wish to specialise particularly in slalom tasks can now compete in FAI Cat1 Slalom events.
For many years now the formula used in slalom scoring has been controversial, and subject to several changes. The current scoring formula is too complicated and too punitive to all but the top couple of pilots, giving them an unfair advantage in the overall competition rankings. This could be argued to be in direct contravention of the spirit of rule 4.29.3. Even the separate FAI Category 1 championships specifically for Slalom have rejected this punitive system in favour of positional scoring.
This proposal is therefore to include a provision within the rules for meet directors to define how they want to score slalom tasks when they submit their task catalogues to the CIMA plenary for approval.
