There is no 6, 7, 8 or 9. There's only zero, five or 10.

You are correct for sound score, but for sequence 95% of all non zero scores are 6-9, this makes the sound score which is 98% 5 or 10, worth more than it would seem in comparision to your raw score prior to normalization.


example in unlimited sound is 12k so a 5 would be 60 raw points and a 10 would be 120 raw points. loss 60 points

Now figure 6 in the unlimited known is 30k a score of 6 would be 180 points a score of 9 would be 270 points a difference of 90 points.


get a 5 instead of a 10 on every sequence flown and it could cost you the contest!!!

in summary getting a 5 instead of a 10 on sound is about the same as getting a 6 vs an 8 on a manuever!

I know this isnt the IMAC forum and is way off topic but.....

The judges arent doing theyre job properly if they are handing out a score spread of between 6 and 9 on all scored manouvers.
When I judge, especially the unlimited guys I am often handing out 4's, 5's even 3's and 2's, some of the manouvers flown in unlimited have very high k factors and have so many elements in them that it would be a very 'nice' judge or an absolutely exceptional pilot to consistently give 6's and above 95% of the time.

If the scores in your comp are looking to have a 3 point range there is a fair chance your judges are impression judging, I judge each manouver on its merit, applying the 1 point per 10 criteria. Throw in mulitiple snap and opposite point roll combinations its not difficult to give even a well flown manouver a cumulaitive deduction of 4 or 5.
On the other hand if its flown only average those deductions will rack up real fast.

I totally agree, and judge that way. we are the 5%. The point I am trying to make is that a 5 vs a 10 on sound can cost you a decent amount of raw points prior to normalization.

Reguardless if a judge gives 6-9 and 0, or 0-10, the scores are normalized and the best pilot wins, unless the flying/scores are really close then the pilot with the quietest plane may win.

Thats quite a statement

[notorious_benny]

OK gotcha....... it is a worry if 95% of judges are impression judging though.

We are lucky, here in Australia we havnt had any comps where the sound score has needed to be applied yet. I am sure they will come, but so far noise isnt a worry at the majority of our IMAC venues.
Having said that, there isnt many Aussie IMAC machines out there that arent already running cannisters and carbon props.

[Dangerous Dan]

My statements are based on crunching numbers, go to Max's one dude into IMAC thread and look at the analysis i did of his scores.

The statement we are the 5% was a little much, honestly even applying 1 per 10 etc etc etc....most pilots fly between a 6 and a 9.

Personally I place my hands on my knees fingers spread and as I see a deduction(1 per 10) line length before and after) radius change , wobble etc.. I pull back fingers. Say I have 6 fingers left the score will be 5.5, 6, or 6.5 (since I canm't pull back 1/2 of a finger).

do you have your own IMAC region or do you fall in one of our regions like canada?

[notorious_benny]

We have the ASAA (Australian Scale Aerobatics Association). I think that makes us our own 'region' if you want to put it that way.
