New FAC algorithm to enter as soon as possible.

Bruno is the man to reply to this, but he's not available at this moment. More news about this soon...

EHM-1617 Iain:
I have been following this topic with interest. I read all of the banter, but I decided that instead of fuelling the fire with talk, I would instead fuel it with some thick, dense, boring analysis of the new FAC algorithm :P

General

We can break the algorithm into two parts, additions and deductions.

Additions:

Total flights - the number of flights you have done is divided by 2
Total online flights - the number of online flights you have done is multiplied by 0.9
Total minutes - total minutes flown multiplied by 0.3

Deductions:

Total extra penalties - the ones you get for crashing, multiplied by 0.7, i.e. 700 per crash
Total penalties

The only ones which are big enough to really make a difference are the Total Minutes addition, the Total Extra Penalties deduction, and the Total Penalties deduction.

Per-flight

Let's look at the algorithm on a per-flight basis.


Flight 1. Imagine a 2 hour PP flight on IVAO. I get 0.5 points for doing the flight at all. I get 0.9 points for doing it online. I get 36 points for flying for 120 minutes. Total additions: 37.4 points. Now the deductions: Say that I exceeded 4500 FPM in the climb. I get 240 penalty points. For this flight, my FAC has now been reduced by 202.6 points, even though the flight was of moderate length, online, and there was only one fault registered by the system - which may well have had more to do with the aircraft type, it may well have been a quick climber - than the pilot's skill.


Flight 2. This flight will be a very long-haul flight. It is 9 hours long, online. 0.5 points for flying, 0.9 points for online.  162 points for flying for flying for 9 hours. There were no penalties. 163.4 points were added to my FAC.


Flight 3. Now let's imagine a flight the other end of the scale. A 45 minute offline flight. Again, I get 0.5 points for flying. I get 13.5 points for flying for 45 minutes. Total of 14 points gained. The flight went very badly. I stalled the aircraft, and exceeded the G-force penalty on landing. A total of 730 points worth of penalties. Net score: 716 points are deducted from the FAC.

Here's the bombshell. Imagine on the very same flight I crashed the aircraft. No other bonuses or penalties are given in the event of a crash (I believe). I would have 700 points deducted from my FAC (1000*0.7). Thus, it would have done less bad to my FAC if I had crashed the aircraft than if I landed hard and stalled during the flight.

Conclusion

I think the figures above speak for themselves. In flight 1, which was not all that bad, I was penalised 202.6 points. Flight 2, which was excellent, I gained not as much as I lost before, only 163.4 points. Flight 3 was terrible. I was penalised 716 points. But, had I crashed, I would only have been penalised 700 penalty points.

My Opinion

Although I recognise that the MT have put a lot of work towards it, I am opposed to this system. I believe it is much too heavy on individual penalties, not heavy enough on crashes, and that the 'bonuses' received for doing lots of flights, long flights, or online flights are so small as to be ineffective. However, I don't see it as a lost cause. With some major tweaking, the values can be evened out, and I believe that it has the potential to become a very fair way of doing things. With the system as it is, many, if not most of us will be well into the 'red'.

I recognise also that it is very very difficult, if not impossible, to create a FAC algorithm that everybody likes; however, I think that what is been proposed is not the best solution to the difficult problem.

If anyone feels I have made a mistake here, please do not hesitate to correct me. As far as I can see though, my analysis is correct.

Is this supposed to be a Virtual Airline or a Virtual Academy for mathematic studies ;)

Tastes a little bit like achievement control and not like "harmony". Good to know that it is only one department of EuroHarmony.

EHM-1617 Iain:
LOL, I was bored. But hopefully you get my point ;)

EHM-1947 Miko:
Yes, of course, Iain, it helps to show the lacks of the system - I am sure it would help to integrate Einstein's antigravity constant - provided that it is compatible with FSUIPC 3.7 :]

(Sorry to all who are tired of my jokes about this topic - this was definetily the last :s)
