Talent 100 one unit marks (1 Viewer)

[Magiccarpet]

Just wanted to ask, for talent 100 calculator do we put one unit subjects as out of 50? Because when I do, the percentile goes to '<25' and the ATAR given is unreasonably low. But when I put the mark out of 100 (doubling it), the ATAR matches up with my other estimates....

Help pls!
