@Yellow cake: As I pointed out in the bbmail, I have thoroughly investigated your drop and it is mainly the fact you had two league losses during that week. The NT part was calculated right, no issues there.
@kozlik4: The one loss last week did have an effect, just not that big. Most of the drop is caused by income from the NT matches which amounted to about 73% of the drop.
Now, it didn't take long to see why that is:
On the 15th, both players were fielded and starters, playing 32 and 26 minutes.
On the 22nd, only one was fielded and wasn't a starter, playing only 13 minutes total.
It is no secret that the amount of minutes played for the NT is in direct correlation on how much the NT part of the merch is affected.
This was very easy to see Kozlik, I expect better from you!
