Yes, I have seen that "Start to end of quarter"
It's like in other word, we normally earning about 30k a day for the first 89 days and on the last day we earn 50k on that day.
I can say the same thing like "earning increase 66.67% from the start to end of quarter" and the 4C come out with a disappointment in the result.
Not sure this is a concerning material or not though. Certainly not. But about the accuracy of the truth is uncertain
