I have a little input, in my opinion service quality should increase according to the target set. The difference in service financing for every 10 points can be almost twice the target (For example, service target 30 costs $ 3,000, service target 40 becomes $ 7500, service target 50 becomes $ 13,000, and on service target 100 costs swell to $ 74,000) and this has been charged from the start we set the service target. The problem is that there is no difference in the speed of growth in service quality, even though we pay a much more expensive fee for it and it seems to remain stuck only increasing 0.5 each week.
