Bonus for silver (25 %)
So I take 25 % of the 5.952 miles (which is 1.488) and add this to the 5.952 basic miles, which is a total of 7.440 miles.
The same with the gold bonus of 100%:
New Yor - Berlin= 3.968 miles
Business Class (1.5) = 3.968 * 1.5 = 5.952 miles
Bonus for gold (100 %)
So I take 5.952 miles plus additional 5.952 miles and have a total of 11.904 miles.
Sorry, if I am confusing you
I have never bought a real business class ticket to confirm this 100%. But from what I have always understood how this stuff works is that Elite Bonus is based upon actual BASE MILES FLOWN. So your factor of 25% and 100% should be multiplied to the Actual Base Miles, which is 3968, not the one after Business class bonus. If I am wrong on this, I am sure someone will correct me.
