Fair points, was looking at the average per session minus the variables, just too many "what if's" and trying to be impartial with the negatives of each profession cos they've all got downsides (i.e.dry skin vs numb fingers vs health probe etc …)
In summary, in average 30 mins session, models cat aside, the rate for an average joe works out to be:
WL: $50
ML: $15 + $50 (tips)

as an ML, you could also easily make up for looks in the service department whereas 1st impressions count as a WL so there's more job certainty and longevity.
I suppose that explains the recent explosion of massage joints dotted around Sydney.
Interesting to hear different perspectives.
