Yeah it's a valid question.

estimated inflows across cy19 at 17.7mil / 4 quarters is 4.4mil per q. Outflows estimate 2.7. So +1.7mil net in/outflows per quarter. 

that's clearly a simple and optimistic estimate as the company would expect it to be last half heavy in revenue. 

but on the other hand the settlement halt last year was clearly not part of the plan and will has had a negative impact on balance. Also the requirements may be much higher than 8-10 mil. So IDK.
