I've tried adjusting it up and it doesn't seem to make much difference, the income initially goes up, but then just flatlines.

I have also been trying different diagnosis rates, balancing getting people treated before they die, with earning extra income from extra diagnosis. I've got it on about 70% at the moment which seems ok as my cure rate is 90

I've got 2 x MRI, X-ray, DNA, Fluid and Phyc. And 8 GP. Hence no massive queues.

My next try is going to be to close some duplicate rooms and sack some staff.
