What you are saying is that management should have said "We are doing very well and our margin has increased significantly for 1h16, yet we still increase our price of 30% and this will flow into 2h16" . Tell that to thousands of customers on face book and see what management will get.
1h16 revenue is 105mil, bal spent only 5mil on employee cost.
85% revenue is infant formula so around 90mil is infant formula. Now apply 30% increase from 90mil. That is 27 mil extra profit. Say conservatively 20mil extra cash. Is bal going to spend all these money on employees and advertising (they spent 2mil on advertising in 1h16)?

What I see is an ebit exceed 30% for 2h16. Bal management will say the reason for increase in ebit % is because of exposure to china etc. Not because of increase infant formula price in Nov 15.
