I do but won't have time to put them in a chart this afternoon. But as an example in the 30th percentile $40K female analysis under the proposed system only $9234 in repayments are made, compared to $44,164 under the current system.

At an abstract level, yes. But after a uni enrolment overshoot in the 2010s that had negative consequences for many (student debt, career detours) I am cautious about saying that current more subdued demand is necessarily a problem, other than that is is putting financial pressure on unis.
