Yes I’ve actually built a spreadsheet and come up with my number precisely. The big mistake is not correcting a mistake the day that it is made. Once it’s in there it sticks around like herpes. I projected I need another 950 miles as of this morning to get back to the 99.5.Hello GlmnAlyAirCar (GAAC), and also MarcG. I found this comment to be very interesting. Indeed, if we look at the individual scores as shown in MarcG's screenshot:
FCW: 0.9HB: 0.2AT: 0.8UFT: 2.0FAD: 0
Plugging these into the formula gives 99.125, which ought not to round to 100. With your scores, GAAC, the calculation gives 99.128: as you suspected, your score ought to be close to MarcG's.
But wait! The actual score is a mileage-weighted average of your daily (total) scores, and since the scoring function is nonlinear, it's not the case that the score based on the average of the parameters is equal to the average of the scores based on the daily parameters! Isn't that interesting? So in fact you cannot go from the five overall parameters to calculate your overall score. You actually have to do the mileage-weighted average (although often the two results are close). I've verified this on my numbers as well. So the overall individual scores are just guidelines.
