Scoring Examples
Scores are calculated based on the simple formula:
d times z
- Where
- d = Total straight line miles between two points (see rules)
- z is a calculated adjustment factor to devalue longer days (see
expression calculation)
The basic formula is simple, but calculating z is clunky, so we recommend
using our Excel Spreadsheet Calculator
Some Scoring Examples
- 50 mile flight on Jan 1st
- d = 1
- z computes to 1
- 50 times z = 50 points
- 50 mile flight on Jan 27th
- d = 27
- z computes to 0.9901
- 50 times z = 50 points
- 51 mile flight on Feb 1st
- d = 32
- z computes to 0.9805
- 51 miles times z = 50 points
- 54 mile flight on Feb 15th
- d = 46
- z computes to 0.9191
- 64 miles times z = 50 points
- 64 mile flight on Mar 1st
- d = 60
- z computes to 0.7828
- 64 miles times z = 50 points
- 88 mile flight on Mar 15th
- d = 74
- z computes to 0.5652
- 88 miles times z = 50 points
