In addition:
I see that OTP-MUC-PVG roundtrip in Business Class is offered for EUR 1250.
One trip gets me (10+50+50+10=) 120 points.
So I just need 4 of such roundtrips a year.
I could make a Senator (480 points) for close to EUR 5000.
This cannot be true.
In my eyes there must be a fare class component built into the calculation.
e.g. fare class C nets 100%; but fare class P just 50% of the calculated points;
