Where you compare against your competition is everything.
Look at the SWE portion of the competition.
If you didn't get at least two deviations from your competition, your going to slide backwards if others can whip you on all the other factors.
The score you see is a modified T-score. The two examples above should show that ... if they posted their SWE scores.
If you want to know where you ended up on the T-score, take the number of points you received, substract 50 and divide the result by 10. That is where you placed on the standard distribution curve ... or on a cumulative distribution curve.
Actually, where you write is VERY important. The closer to the 'average' score, the more you 'move' on the list. The folks at either end of the list tend to move less. To put things into perspective in the end, ONE MORE question correct equates to 6 months sea time or a good conduct/LOC or 1 year TIS or 6 mos TIG or an average marks bump of 5 points on every mork. Of course, one less question has the same affect. Although there are slight variations every year, in the end a difference of one question is normally worth 0.8 to 1.2 points.
