<div>Wrong question.<br>
The real question is why round at all? Once you allow half point deductions in the judge's mind, just let them stand.<br>

<p class="MsoNormal">Some ideas and changes are just plain stupid! There I said it :)<br>
<br>
I have always hated the fact that some judging criteria and downgrades<br>
were different in FAI and AMA. Makes judging which is a tough job to do<br>
right even tougher. You have to know 2 different sets of rules and in<br>
the long run only lowers the accuracy of judging, most likely more so<br>
for the FAI fliers. But that is another can of worms.<br>
<br>
I thought that allowing 1/2 points in FAI sounded like a good idea, we<br>
are used to it in the rest of the classes. And since the FAI pilots are<br>
in most part the better fliers they are more likely to make the 1/2<br>
point errors as compared to the greater inaccuracies usually seen in the<br>
lower classes.<br>
<br>
But wait an 8.5 becomes a 9, and a 9 is still a 9 ??????<br>
<br>
So just to prove how silly this idea can be I used Scott's scoring<br>
program and ran a fictitious contest with 2 flyers and 2 rounds. I used<br>
a couple of friends as contestants so to not offend anyone. I also had<br>
to use the masters sequence as an example, as the program automatically<br>
rounds up FAI scores.<br>
<br>
Hopefully the PDF files are attached.<br>
<br>
Each flyer received identical scores in each of their 2 flights. AR<br>
received all 7.5's except one maneuver which was an 8.5, and DL all 8's<br>
. In round 1 scores were not rounded up and in round 2 the scores were<br>
rounded up as they would automatically be done in FAI.<br>
<br>
Look at the files for AR round 1 and DL round 1. It would seem pretty<br>
obvious who should win that round and without rounding up AR gets a<br>
947.75 to DL's 1000.<br>
<br>
Note that every maneuver but one was judged higher for DL.<br>
<br>
Now look at AR round 2 and DL round 2 rounded up. The same exact judges<br>
scores with only 1 maneuver scored higher for AR, but due to the<br>
rounding up AR wins the round 1000 to 989.86.<br>
<br>
Now this is the extreme and unlikely to actually happen in a contest to<br>
this extent but just the fact that it works this way makes the whole<br>
idea of rounding up ridiculous.<br>
<br>
Is there really an argument that this is a good thing?<br>
