How accurate are SAM/UMAX? (2 Viewers)

[Stephie-Rae]

Matrix: 94.65
Actual ATAR: 94.35

Pretty close.

 

[M@ster P]

not that accurate

Umax: 94.5
Sam: 94.6

actually: 93.65

SAM, UMAX and Einstein all estimated between 93.15-93.25. I ended up with 93.05, so only 0.10-0.20 off.

SAM: 97.45
Umax: 98

ATAR: 98.05

They underestimated me! Shame on them...

UMAX was unbelievable. Predicted 99.85 ... which was exactly what I got. >.<

SAM was a little disappointing. It predicted 99.75 UAI, which wasn't too far off I suppose. =3

 

[alice09]

einstein 09 was right on the money 4 me with 99.10 and it was my highest predictor sam and umax underestimated with 98.75 and 98.95

 

[annabackwards]

UMAX estimate - 99.05
JUAI estimate - 99.20
Einstein estimate - 99.25
SAM estimate - 99.00

Actual ATAR - 99.00

 

[Jcc Lin]

exact!

Does anyone know the difference in the calculation methods used by each of the calculators? They're all based on the same underlying UAC scaling statistics, so why is it that they can be sometimes significantly different from each other?

sorry to bump this thread with my less than 97 atar...

but UMAX said 91.85 and thats what i got. sam said 90.85
